L300-TC Thermocouple Data Logger

with 8 channel10A Relay Alarm / on-off output

Specifications

An 8-channel self calibrating data logger with up to 0.01C resolution.
8 x 10A relay o/p's
USB PC interface + software.

The thermocouple thermometer with alarm / on-off control can be used in conjunction with a PC to provide accurate, versatile 8 channel measurement, scanning and logging of measured values and alarm / on-off control of up to 8-zones simultaneously. It can also be used as a "stand alone" indicator / logger and incorporates a digital display of measured temperature.

The in-built, self-calibration facility for the thermocouple version is a rapid and convenient method for on-site calibration and does not require and additional equipment other than a special, external link.

The unit is designed to provide exceptional stability with high measurement resolution and represents an ideal crossover between plant practicality and laboratory performance at a very competitive price.

The PC software supplied with the instrument allows control, configuration, measurement, logging, charting, alarm and relay configuration and calibration functions.
