The Therma D41 and D45 panel thermometers offer high accuracy with excellent long term stability. The large, 3½-digit LED display offers a wide temperature measurement range with clear indication of readings and a choice of 0.1°C or 1°C resolution. The panel thermometers are housed in a 48 x 96mm DIN size, glass-filled plastic case with a minimal 88mm behind the panel space requirement.
Both models are available for 230 volt AC, 115 volt AC or 12 to 30 volt DC/AC supply. All connections are made via rear plug and socket screw terminals. ETI offers an extensive range of interchangeable industrial thermocouple type K probes, to view a small selection click here.

Panel/wall mounted thermometer probes
Thermometers are only part of the system, of equal importance is the design of the temperature probes used to physically measure the item. ETI manufactures an extensive range of type K or J thermocouple probes, industrial thermocouples for the plastic moulding industry and heavy duty industrial probes to compliment our range of mains-powered panel and wallmounted thermometers
Choose the ones that suit your needs from many options including:
• high temperature probes
• air probes
• surface probes
• submersible probes
• mixer probes
• mineral insulated probes
• wall/bulkhead probes
• fabricated probes
• probes with IDF fitting
• heavy duty probes
accessories
The Therma SP selector switch units are housed in a standard DIN case (48 x 96mm). The selector switches may be used to extend the measurement capabilities of the Therma D41 and D45 thermometers, allowing either up to 6 or up to 12 thermocouple sensors to be coupled to a single instrument.
