NTC-1900

FEATURES

• 12.5mm / 0.5” LCD digit height

• Uses an external probe supplied (cable length
approx. 1m / 3 ft)

• °C and °F measurement

• Temperature measurement range of probe

-40°C (-40°F) to +105°C (+221°F)

• Solderless setup

• Requires 32.5mm (1.28”) diameter cut-out

• IP67 / NEMA 4X protected

The EM32-1900 is an easy to mount LCD digital thermometer. The module

uses an NTC temperature sensor to ensure high accuracy over a wide

temperature range. The module uses an external sensor with a maximum

temperature range of -40°C (-40°F) to +105°C (221°F). This product is designed so no soldering is required. The module features a round

metal bezel, requiring a 32.5mm (1.28”) diameter cut-out. It is secured with the nut provided. Protection from the front to IP 67 / NEMA 4X

standards is achieved by placing the rubber seal between the module and panel during assembly.

* Using external NT sensor with 10kΩ @ 25°C and a 24 to 85°C Beta value of 3977. The module may require recalibration. To ensure maximum accuracy, recalibrate
periodically. Calibrate the module at the top end of the measurement range.
** Do not apply more than 28V, as this may damage the meter.

SAFETY

As the NTC temperature sensor is a passive device, no voltages should be applied to the input terminals of the EM32-1900. The user must

ensure that the incorporation of the meter into the user’s equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements

for Electrical equipment for Measuring, Control and Laboratory Use).
