Explosion-proof instruments>> Temperature Controller
The ASHE Series AHT range of microcontroller based Digital Humidity and Temperature Controllers are compact, rugged and reliable instruments designed for accurate measurement and control applications.

The Indicators accept the Humidity and Temperature signal from the ASHE HTP-1 Probe as their input and display Relative Humidity and Temperature parameters on a 4-digit seven-segment LED digital display. Up to four relay outputs are available as control options, each of which can switch a load of up to 10 Ampere rating. The Relays may be assigned for either Temperature, or Relative Humidity, or both. The Controllers are available in individual and combined parameter options and operate on AC or DC power supply, as required. Options include analog retransmission signals, weather-proof / flame-proof executions, etc.

All ASHE instruments carry a lifetime warranty against defects in components and workmanship.
