Hydrogen sulfide is a chemical compound with the formula H

S. It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs

Hydrogen sulfide

The Model 30 is an analyzer for the measurement of toxic gases in the
workplace. This analyzer is unusual since it is easy to calibrate, has a fast response and has only one step to send logged (optional) data to a PC.

It uses electrochemical sensors for the measurement of ppb to ppm levels of selected toxins. It has many unique features.

We introduced the first commercial photoionization based instrumentation for industrial hygiene measurements of 1 ppm of vinyl chloride in 1974. Nearly 40,000 of the portable PIDs have been sold throughout the world for IH and safety measurement.

More than 50 United States Environmental Protection Agency and Occupational Safety & Health Administration (OSHA) methods based on PID have been published in the Federal Register.

Model 30 Electrochemical Sensor Analyzer

This analyzer has features and pricing like the early Model 102. The electronics have been upgraded, the lamp is the same long lifetime 10.6 eV but it does not have the capability to add 9.5 or 11.7 lamps. It does not have BT or WiFi. It does have a 2.4" OLED Display and LiPolymer battery. The Model 103 has many more features than this particul ar model.

Model 90 Basic Photoionization Analyzer

The Model 112 is a low cost continuous VOC Analyzer. It has an optional 4-20 mA output, a single programmable setpoint, larger pump & an industrial NEMA 4 enclosure.

This 112 the choice of one 9.5 or 10.6 eV lamp, Operator's Manual, configuration software and RS232 cable.

Model 112 Fixed System PID

The Model 202 is a reliable & rugged dual beam non dispersive infrared (NDIR) monitor-ing system used primarily for the measurement of CO2, CH4, CO, & N2O hydrocarbons.

The PID Analyzers Infrared gas analyzer uses a dual beam interference filter instrument and has been designed with the process and plant environment in mind.
