Description
The E+E EE300Ex-M1 is an intrinsically safe humidity and temperature transmitter that can be installed entirely in Zone 0/20 or Class I–III Div 1 hazardous areas. With its stainless steel remote probe it measures 0–100% RH and −40 to +180 °C at pressures up to 20 bar, with accuracy as good as ±(1.3 + 0.3% of reading)% RH, and it calculates dew point, absolute humidity and other moisture values.
Versions with ATEX/IECEx/KCs approval also measure water activity and ppm water in insulating, lubricating and hydraulic oils. It has two isolated 4–20 mA outputs and an optional display, and holds ATEX, IECEx, FM and KCs approvals.
Argonmark Ltd supplies E+E Elektronik instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
