Hanna HI83399 Multiparameter COD Photometer and pH Meter

Hanna HI83399 water and wastewater multiparameter photometer with COD and pH

The Hanna HI83399 is a benchtop and portable multiparameter photometer for water and wastewater with 98 methods, including four chemical oxygen demand (COD) ranges, and a digital pH probe input. It is the broadest single instrument in the Hanna photometer range covered on this page. Seven Star LLC is an independent supplier in Muscat and is not affiliated with the manufacturer.

The part number identifies the COD-capable model with five optical channels and support for both round 24.6 mm cuvettes and 16 mm vials. Reagents, COD vials, the reactor for digestion and the digital pH electrode are separate items.

HI83399 technical specifications

How the HI83399 works

In photometer mode the HI83399 passes LED light through a reacted sample and calculates concentration from absorbance for the chosen method; five wavelength channels allow a wide library covering colorimetric, turbidimetric and digestion-based tests. COD follows an EPA 410.4 adaptation in which sample is digested in a vial in a heated reactor and then read by the meter.

In probe mode, a digital pH electrode with intelligent identification gives pH from -2.00 to 16.00 with two-point calibration from five available buffers, so one instrument can cover wet-chemistry and pH checks on the same bench.

Where HI83399 fits: sensors, accessories and related models

A typical COD set-up includes the Hanna reactor (the manual references the HI839800 at 105 °C and its HI740217 safety shield for digestion methods), 16 mm digestion vials of the right COD range, pipettes and a compliant waste route for used digestion vials as described in the vial safety data sheet. The CAL Check feature validates the optics.

The smaller HI83326 is the pool-focused cousin with 17 methods and three channels.

HI83399 family comparison

If your laboratory only needs pool parameters the HI83326 is enough; for wastewater COD, silica, heavy metals and nutrient work choose the HI83399.

Selection and ordering checklist for HI83399

• List all parameters needed and verify them against the 98-method library
• Choose COD ranges (0 to 150, 1500, 15000 mg/L or 60.0 g/L) and the corresponding 16 mm vials
• Quote the digestion reactor and safety accessories
• Add a digital pH electrode, reagent sets and CAL Check cuvettes
• Plan a waste route for digested COD vials
• Confirm USB flash or PC export needs

Installation, calibration and maintenance of HI83399

Position the meter on a stable bench away from the reactor to avoid heat and vibration, charge the battery or use the USB adapter, and follow the tutorial for each method. For COD, preheat the reactor to the temperature stated in the vial method, digest, cool the vial and read it only after it has reached ambient.

Clean cuvettes and vials carefully, wipe them dry, and never read a vial with condensation. Calibrate the pH electrode with fresh buffers, keep it in storage solution and replace it when response degrades. Validate with CAL Check cuvettes on a schedule.

Digestion methods carry real safety obligations: use eye protection, handle hot vials with the safety shield and tongs, and dispose of used vials as hazardous waste. Label vials with sample IDs before heating because contents can change colour after digestion.

Where results will be reported to a regulator, keep the log, calibration data and reagent lot numbers together so that audits can reconstruct how a value was produced.

Typical applications of HI83399 in Oman and the GCC

In Oman and the GCC the HI83399 is used in sewage and industrial effluent laboratories that need COD, ammonia, nitrate, phosphate and metals on one bench, in desalination and power-plant laboratories, in environmental consultancies and in university teaching labs. Its 98 methods save buying separate single-parameter photometers.

Because the same meter handles COD and routine nutrients, a small laboratory can standardise on one calibration and validation regime.

Information to send with an RFQ for HI83399

• Quantity and the list of parameters to be measured
• COD range(s) and number of tests
• Reactor, reagents, vials and CAL Check cuvettes
• Digital pH electrode and buffers
• Delivery location and lead time
• Project or tender reference

Storage, handling and spares for the Hanna HI83399

Store the Hanna HI83399 in its case in a clean, dry place. Keep probes, electrodes and reagents as described in the user manual, as many of them need a storage solution or have a limited shelf life. In the GCC climate, keep reagents away from heat and direct sun and check expiry dates before use.

• Calibrate the instrument with fresh standards at the interval your procedure requires.
• Rinse probes and sample cells after each use and inspect them for scratches or deposits.
• Keep spare consumables, such as reagents, standards, cuvettes and electrode solutions, in stock.
• Record calibration results so that drift or probe ageing can be seen early.

When you order the Hanna HI83399, list the consumables and standards you need in the same RFQ, so the instrument can be used from the day it arrives.
