Oxygen Transmitters & Analyzers
Loop-powered (4-20mA) electrochemical and fuel-cell oxygen instruments covering trace ppm levels up to 100% O2, in fixed, portable, and OEM-module formats.
OxyTran 100 Oxygen Transmitter
Compact, loop-powered (4-20mA) fuel cell oxygen transmitter measuring 0-100% O2, with an IP65 enclosure and stainless steel flow-through cell.
Portable Oxygen Transmitter
Portable electrochemical oxygen transmitter delivering fast, accurate trace and percent-level O2 readings on an LCD display — ideal for spot-checks in industrial gas analysis.
O2 Tracer
Economical, loop-powered (4-20mA) fuel cell oxygen analyzer measuring 0-100% O2 (typ. 0-25%), calibrated with gas or ambient air for general industrial monitoring.
O2 Tracer D
Panel- or duct-mount oxygen transmitter delivering continuous 4-20mA O2 output for ongoing process monitoring.
O2 Tracer DIS R Oxygen Transmitter
Two-wire, loop-powered (4-20mA) oxygen transmitter with remote configuration, offered in multiple percent-range options for industrial O2 monitoring.
O2 Tracer R with Alarms
Room-mount oxygen monitor with built-in high/low alarm relays, built for personnel safety monitoring in confined or oxygen-depleted spaces.
OxyTrans II Series Oxygen Transmitter
Loop-powered oxygen transmitter with single-point calibration, offered in ppm and multiple percent ranges, with optional ATEX explosion-proof certification.
OxyTrans LC OEM
Compact, low-cost OEM oxygen transmitter module designed for integration into third-party instrumentation and process skids.
Hydrogen Transmitters (Zero-Oxygen Environments)
Loop-powered hydrogen transmitters purpose-built for anaerobic, zero-O2 process environments.
Hydro-Trans Hydrogen Transmitter
Loop-powered hydrogen transmitter for continuous H2 monitoring in process gas streams. Note: the live product page’s on-page heading currently reads “Thermal Conductivity Transmitter” instead of the model name — worth fixing so search visitors see the name they searched for.
H2Trans ZO
Loop-powered (4-20mA) hydrogen transmitter for zero-oxygen environments, with simple single-point calibration for anaerobic process monitoring.
H2 Trans Hydrogen Transmitter
Loop-powered (4-20mA) hydrogen transmitter for zero-oxygen environments, with simple single-point calibration for anaerobic process monitoring. (Note: the image on the live H2 Trans page is currently a duplicate of the H2Trans ZO photo — worth swapping in a distinct product photo.)
Carbon Monoxide & Carbon Dioxide Analyzers
Loop-powered transmitters for continuous CO and CO2 monitoring in industrial and safety applications.
CO Tracer
Loop-powered carbon monoxide transmitter for continuous CO monitoring in industrial and safety applications.
CO2 Tracer
Loop-powered carbon dioxide transmitter for continuous CO2 monitoring in industrial process and environmental applications.
