Systech
Oxygen measurement is the core of Systech, whose instruments are also labeled Systech Illinois. Its process analyzers cover oxygen from fractions of a ppm up to percent levels in industrial gases, and its laboratory instruments test food and pharmaceutical packaging. Seven Star LLC lists Systech ZR810 zirconia oxygen analyzers and EC91 transmitter spares, and sources them for gas plants and laboratories in Oman and the GCC.

Oxygen measurement is the core of Systech, whose instruments are also labeled Systech Illinois. Its process analyzers cover oxygen from fractions of a ppm up to percent levels in industrial gases, and its laboratory instruments test food and pharmaceutical packaging. Seven Star LLC lists Systech ZR810 zirconia oxygen analyzers and EC91 transmitter spares, and sources them for gas plants and laboratories in Oman and the GCC.
Systech product families
The process line is built around the ZR800 zirconia analyzers, stated by the manufacturer for 0.1 ppm to 100% oxygen, and the EC900 electrochemical process analyzer. The packaging line includes the GS6500 and GS6600 headspace analyzers, Gaspace Advance, and the 8101e and 8107e oxygen transmission rate testers. On our site you will find the ZR810 for nitrogen and for argon service, the EC91 amplifier PCB (part 091-024) and the 090182 trace oxygen cell.
Ordering Systech parts: what we need
For an analyzer, send the background gas, the measuring range, sample pressure and whether a pump or flow alarm is required. For spares, send the part number and the model and serial number of the transmitter they go into.

Frequently Asked Questions
What is the difference between Systech zirconia and electrochemical oxygen analyzers?
A zirconia cell, as in the ZR800 series, runs hot, responds quickly and covers a very large span from trace ppm to percent levels. It is not suited to gases that burn at the cell temperature. An electrochemical cell, as in the EC900 and the older EC91, works at ambient temperature and is a consumable that must be replaced periodically.
How do I identify the right oxygen cell for an EC91 transmitter?
Use the part number on the cell itself or in the transmitter manual; the trace stainless-steel cell listed on our site is 090182. Cells differ by measuring range and by the gas they tolerate, so also send the transmitter model, its serial number and the gas being measured. We check the match in the manufacturer's documentation.
Does the background gas matter when ordering a ZR810?
Yes. The analyzer is configured for its background gas, and flow components and calibration differ between, for example, nitrogen and argon. Reducing or flammable gases react on a hot zirconia cell and distort the reading, so always state the full gas composition. We confirm suitability with the manufacturer before quoting.
What should I send for a quotation on Systech equipment?
For analyzers: gas, range, sample pressure and temperature, required outputs and alarms, and supply voltage. For spares: the part number, such as 091-024 for the EC91 main amplifier PCB, plus the instrument model and serial number. A nameplate photo is the quickest way to give us all of it.
Is Seven Star LLC a distributor of Systech?
No. Seven Star LLC is an independent industrial supplier based in Muscat. We source Systech analyzers and spares through commercial channels, check the model or order code against the manufacturer's documentation before ordering, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order, on request.
