Name: RKI T2A Fixed Gas Transmitter
Brand: RKI Instruments
SKU: 65-2698
Price: 1140.0 USD
Availability: InStock

The RKI T2A is a loop-powered, two-wire fixed gas transmitter built around electrochemical sensing, covering an unusually broad library of toxic gases — from common ones like CO, H2S, and NH3 to more specialized targets like HCl, HCN, ozone, phosphine, ethylene oxide, and arsine. A 3-character 7-segment display and magnetic switches let technicians check readings and configuration without opening the enclosure.

The T2A draws just 35mA max at 12-35VDC and outputs a standard 4-20mA loop signal, with an aluminum enclosure and 303 stainless steel sensor housing certified cCSAus Class I Division 1 & 2 Groups B, C, D and rated NEMA 3/4/4X/7/9 for -40°C to 60°C operation. Its broad gas library makes it a common fit for facilities standardizing on one transmitter platform across many different toxic gas monitoring points.
