Honeywell BW Solo Serviceable Single-Gas Detector
Description
Honeywell BW Solo single-gas detector with serviceable sensors
The Honeywell BW Solo is a compact single-gas detector designed to be serviced rather than thrown away. Sensors, batteries and sensor filters can be changed without opening the instrument, which lowers lifetime cost and keeps detectors in service for years. Seven Star LLC supplies the BW Solo in Oman and the GCC as an independent supplier in Muscat.
The BW Solo is offered with a very long gas list. The newer 1-Series sensors cover H2S, CO, O2 and CO2, and the 4-Series sensors extend the range to chlorine, chlorine dioxide, ethylene oxide, hydrogen, hydrogen chloride, hydrogen cyanide, hydrogen fluoride, ammonia, nitric oxide, nitrogen dioxide, ozone, phosphine and sulfur dioxide. One housing therefore serves refinery, water treatment and chemical users alike.
Each BW Solo carries a single sensor, so the gas you specify when ordering the BW Solo defines what the instrument can do. A wireless version adds Bluetooth connectivity to the manufacturer’s mobile apps.

BW Solo sensor ranges and working temperatures
The following ranges are taken from the datasheet. Working temperature is given in °C and differs by sensor, so a detector with, for instance, an ammonia or chlorine cell has a narrower window than one with an H2S or CO cell.

|---|---|---|---|
| H2S (1-Series) | 0 to 200 ppm | 0.1 ppm | -40 to 60 |

How the BW Solo is built and how it behaves
The BW Solo has one-button operation and a display that is easy to read in several languages; the datasheet lists English, French, Spanish, German, Italian, Russian, Japanese, Chinese, Korean, Portuguese and Dutch. At activation it checks the sensor, circuitry, battery and the audible and visual alarms, and it continues to test the battery while running.
Users can reset TWA, STEL and peak readings, change set points, latch alarms, switch on IntelliFlash or a non-compliance indicator, set calibration or bump-test reminders and assign a worker and location. These options are applied through the configurator tools rather than from the keypad.
Fleet management and related Honeywell portable detectors
The BW Solo is compatible with the IntelliDoX docking system. Docking modules run bump tests and calibration automatically and store the records, and with the Safety Suite Device Configurator software an entire fleet can be maintained from a desktop. The wireless version streams readings through a phone to the manufacturer’s real-time monitoring software, giving a supervisor remote visibility on alarm status and location.
Seven Star LLC also supplies the BW Icon fixed-life multi-gas detector, the BW Max XT II pumped four-gas unit, the BW Clip series, the BW RigRAT area monitor and the ToxiRAE Pro. Where a worker needs one gas only and the sensor may need changing, the BW Solo is the serviceable alternative to the throw-away BW Clip.
Selection checklist for the BW Solo
- Pick the single target gas and its range; the sensor series follows from this.
- Choose the standard or wireless version according to whether remote alarm visibility is needed.
- Compare the sensor working temperature in the table with your hottest and coldest working areas.
- Plan for battery life: O2 1-Series models run about six months and CO2 models about two months.
- Check the approval markings against your hazardous-area classification.
- Decide how bump tests will be recorded and whether IntelliDoX docking is justified by fleet size.
Servicing and calibration practice for the BW Solo
Because the BW Solo is designed to be serviced, hold a small stock of the sensors you run and replace them according to your calibration records and the warranty terms in the datasheet. Bump test before each day’s work or at the interval your own procedure sets, calibrate when the bump test fails or the interval expires, and keep sensor filters clean.
When you order sensors or spares, give the exact gas, series and range so that the correct part is supplied. Keep removed sensors out of the sun and away from solvents, and log serial numbers against the instrument they came from.
Where the BW Solo is used in Oman and the GCC
In Oman and the Gulf the BW Solo is common for H2S monitoring in oil and gas production and processing, CO checks in power plants and workshops, ammonia and chlorine monitoring in refrigeration and water treatment, and a range of toxic gases in petrochemical and fertiliser operations. The IP66/68 rating helps in sand, dust and washdown conditions, and the rugged form factor suits clipping to a collar or harness.
Because the temperature window depends on the sensor, a unit for ammonia or chlorine in a hot, shaded yard needs particular care, and the working range in the table should be compared with local conditions.
Information to send with an RFQ for the BW Solo

About brand
Honeywell is the American industrial technology group whose products on this site cover gas and flame detection, pressure transmitters, flow measurement, gas metering, fire alarm systems and helicopter rotor balancing equipment. Its roots go back to a thermostat business in Minneapolis in 1885 and to Mark Honeywell's heating company, which merged with it in 1927. Several brands we list have joined Honeywell over the years: Gent fire systems of Leicester (part of Honeywell since 2005), Chadwick-Helmuth (a Honeywell business unit from 2002) and Elster gas metering (acquired around the end of 2015).
Seven Star LLC is an independent supplier in Muscat. We list Honeywell gas detectors and sensors, transmitters, Elster gas meters and flow computers, Gent fire alarm equipment and Chadwick-Helmuth balancers, and supply them and their spares in Oman and the GCC by part number.

Gas detection uses two basic approaches. Point detectors such as the Sensepoint XCD measure the gas at one location, with a catalytic or infrared sensor for flammable gas and an electrochemical cell for toxic gas such as H2S. Open path detectors such as the Searchline Excel send an infrared beam across an area up to a few hundred metres long and detect a gas cloud anywhere along it. Infrared sensors cannot be poisoned the way catalytic beads can, which matters on sites with silicones or H2S.
Where Honeywell products are used
In Oman and the GCC, Honeywell gas detectors protect wellheads, gas plants, refineries and tank farms. Elster meters and flow computers measure gas at city gate stations and in industry. Gent systems are installed in commercial buildings, hospitals and hotels, and Chadwick-Helmuth balancers are used by helicopter operators.
Ordering Honeywell products: what we need
Send the part number from the label (for example 02104-N-XSSA or SPXCDASMTXF). For gas detectors, add the gas, range, output and certification. For gas meters, add size (DN), flow range and pressure rating. For Gent equipment, add the panel type and loop protocol.

FAQ
Questions about the Honeywell BW Solo Serviceable Single-Gas Detector
Answers from our engineering team on installation, compatibility and integration.
01What is the difference between 1-Series and 4-Series sensors in the BW Solo?
The datasheet offers 1-Series sensors for H2S, CO, O2 and CO2, and 4-Series sensors for the wider gas list such as NH3, Cl2, SO2, NO2 and PH3. The 1-Series models are slightly thinner, at 3.6 cm against 4.1 cm, and carry a three-year warranty against two years.
02Can sensors and the battery be replaced in the BW Solo?
Yes. The BW Solo is described as the easiest single-gas detector to service, because sensors, batteries and sensor filters can be replaced without taking the instrument apart.
03Does the BW Solo have wireless connectivity?
A wireless version is available. It uses Bluetooth Low Energy to pair with the Honeywell Safety Communicator and Device Configurator apps, so readings and alarms reach the manufacturer's Safety Suite software.
04How long does the BW Solo battery last?
The datasheet gives a typical battery life of 12 months, falling to 6 months with the 1-Series oxygen sensor and 2 months with the 1-Series CO2 sensor.
05Which approvals are listed for the BW Solo?
The datasheet lists Class I Division 1 Groups A to D T4, Class II Division 1 Groups E, F and G, ATEX, IECEx and Inmetro Ex ia IIC T4 Ga marking, plus ABS type approval. The sensor fitted can restrict the temperature window, so check the table.
