EM32-1900 Round Hole Mounting ORDERING INFORMATION Standard Meter EM32-1900 Thermometer Thermistor Probe 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 -40C (-40F) to +105C (+221F) 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 -40C (-40F) to +105C (221F). 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.
