CI Series Bimetal Thermometers (±1% of span)

This series is tamper proof, hermetically sealed and has the Maxivision® dial. The connection locations are rear and lower. The CI series of Ashcroft® industrial bimetal thermometers was designed for applications where external adjustment or pointer reset are not desired. The hermetic seal prevents entry of moisture into the casing, thus minimizing the possibility of fogging inside the case. The Maxivision dial provides accurate temperature readings.

EI Series Bimetal Thermometers (±1% of span)

This series has a hermetic seal and an external adjustment in the rear of the case. As with other Ashcroft® industrial bimetal thermometers, it has a Maxivision® dial which eliminates parallax by placing the pointer on the same plane as the graduations. The connection locations are rear, lower, and Everyangle.™  The hermetic seal prevents entry of moisture into the casing, thus minimizing the possibility of icing or fogging inside the case. The window stays clear, and with the Maxivision dial, precise readings are certain.

EL Series Bimetal Thermometers (±1% of span)

This series - liquid filled - is available in 3" rear, 5" rear, and 5" Everyangle™ connections. The external adjustment is standard. The Ashcroft® liquid-filled thermometer provides the same features as the EI style with the added benefit of liquid filling. The potential wear problem caused by excessive vibration is minimized through dampening and the instrument life is prolonged. The liquid medium also improves readability.

FT Series Pocket Test Bimetal

The sturdy 1" test thermometer offers accuracy and versatility normally found in larger, more expensive instruments. The Ashcroft® pocket test thermometer provides precise temperature readings in solids, liquids, and gases - such as frozen food, meats, vats, cookers, stills, air-conditioning ducts, and in numerous other places. Protective clip-sheath fastens securely to a pocket, holding the thermometer safely, yet readily accessible. An external adjustment feature permits simple zero reset in seconds by clamping hex nut under head firmly and rotating the head by hand.

2400E and 2410E Digital Thermometer (±2° NSF per C-2)

The Ashcroft® 2400E and 2410E digital thermometers are compact, solid state temperature measurement and display devices. The 2400E measures temperature with a laser-trimmed 2000 ohm RTD contained in a stainless steel probe. The signal from the RTD is conditioned and sent through an analog-to-digital converter and is shown on a LED display. The unit is powered by 6 Vdc, which is delivered through a power supply that operates on 110 Vac (220 Vac and 24 Vac are optional). When more than one indicator is required, two thermometers can be operated by one 110 Vac supply. The power supply is UL recognized and the complete unit is NSF approved for class C-2 applications.
