The Land GMT system has been designed to make accurate temperature
measurement on glass molds.
It replaces the former Land YQA system and
provides similar measurement precision from a much more portable, user-friendly
instrument.
Additionally, it provides a powerful data logging capability with storage
for up to 1000 measurements, which can be downloaded into spreadsheet
programs using the supplied MS Windows download software.

GMT comprises a hand held thermometer and processor, inter- connected by a short rugged, detachable cable.
The thermometer has an infrared detector with associated electronics and a rigid fibre optics probe, the tip of which is momentarily touched to the hot surface to make a measurement.
The processor has an easy to read LCD graphics display, “capture” and operating buttons, and a data store. A single 9V battery powers the whole system.
Features
New: Readings can now be logged with a time and date identifier - allowing
a wider variety of analyses to be performed on the temperature data.
Fast, easy, single button measurement: Touch the probe tip to the target
surface and press the capture button. The temperature is taken and displayed
(and in logging mode, stored).
Accurate: Spectral response is 0.8 to 1.0µm. Short wavelength
operation minimizes errors due to emissivity and/or optics contamination.
Powerful data logging: Up to 1000 readings can be stored, each
reading comprising: temperature, time and date, emissivity and an optional
location identifier. The stored data can be downloaded via a RS232C port to
PC for spreadsheet analysis using the supplied MS Windows download software.
