ToxiBossTM- Toxic Gas Sensor

Contact Sales
ToxiBoss is a wall mounted gas sensor with interchangeable sensing heads to cover a wide variety of toxic gas situations. It is approved intrinsically safe for hydrogen (Group B) environments. Its Class I, Div 1 and 2, Group BCD approval means that it may be used in any hazardous gas environment, except acetylene. And, being intrinsically safe, it can be serviced in place without having to disconnect power or to undertake a costly declassification of the area. Also, the ToxiBoss can be installed in Div 2 applications without the added cost of sealed conduit.

Pick any one of the following sensing heads to suit your particular needs.

ToxiBossToxiBoss
The ToxiBoss unit is normally supplied with a NEMA-4X fiberglass and SS weatherproof housing. For indoor use it can also be purchased with a smaller aluminum housing with the size and appearance of a domestic smoke alarm. Use the standard NEMA-4x version where moisture and dirt are expected. Pick the aluminum version for decorative appearance, ease of wiring and fast access for wiring and adjustments. Both styles have sealed electronics to absolutely protect the integrated circuit components from corrosion.

The ToxiBoss is intended for ceiling or wall mounting. It produces a linear 4-20ma-output signal; excitation 9.5-30VDC, drawing 50ma, 3-wire hookup.

ToxiBoss arrays can be monitored individually by Rel-Tek's TelEcon trip-point relay modules, while large arrays can be monitored, logged and networked using Rel-Tek's Millennia-DX® PC-based SCADA systems. They can be fitted with calibration adapters for automatic calibration using Rel-Tek's unique MagiKalTM utilities (patents pending).
