K type thermocouple probeThe 2103 series meters are portable anemometers for use with Hot Wire or Vane type sensors. pitot tube and thermocouple connectionsThis page deals with Hot Wire sensors but the same hand set can be used with a Vane sensor.
They are used to perform measurements in air conditioning, heating, ventilation and similar industrial applications, They measure the air velocity based on the cooling of a small hot element in the tip of the probe. The instrument calculates and reads out directly in air velocity. The volume flow is calculated from the dimensions of the duct or pipe which you enter into the meter. There is connection for platinum resistance thermometer so that the instrument can also be used as a precision thermometer. There are two version of the handset 2103.1 standard and 2103.2 with data logging. The data-loggers they can store up to 36000 samples which can be transferred from the handset to PC via the RS232C and USB serial ports. The logging interval, baud rate can be configured by the user, The instrument can also be used to acquire real time measurements to a PC or a printer. The max min average function calculates maximum, minimum and average values according to the user requirements. Other functions include REL - relative measurement and HOLD - current value. You have a choice of 4 different hot wire sensor depending on the range required
