ToxiBossTM – Toxic Gas Sensor
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.
| Gas | Range | Units | Sensor model | Head Designation |
| CO | 0-500 | ppm | TB-CO/500 | TBH-CO/500 |
| NO2 | 0-10 | ppm | TB-NO2/500 | TBH-NO2/500 |
| H2S | 0-50 | ppm | TB-H2S/500 | TBH-H2S/500 |
| H2 | 0-25 | ppm | TB-H2/500 | TBH-H2/500 |
| Cl2 | 0-10 | ppm | TB-CL2/500 | TBH-CL2/500 |
| SO2 | 0-10 | ppm | TB-SO2/500 | TBH-SO2/500 |
| O2 | 0-100 | % | TB-O2/100 | TBH-O2/100 |
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).
