GTF300: 2 teflon-isolated, helically winded thermoelement wires with a dia. of 0,2mm each, length approx.
1m with miniature flat plug, free from thermo-voltage. Sensor suitable for surface and immersion
measurements. Response time in liquids 0,3sec. Measuring range: -65 to 300°C.
Display: approx. 13 mm high, 3 1/2digit LCD
Nominal temperature: 25°C
Working temperature: 0 to 45°C, please avoid quick temperature changes, if possible, otherwise a temperature
adjustment time of approx. 15 minutes has to be taken into account.
Atmospheric humidity: 0 to 80 % r.F. (not condensing)
Storage temperature: -10 to 70°C
Power supply: 9V-battery type IEC 6F22 (included)
Battery service life: approx. 700 operating hours
Low battery warning: "BAT" displayed automatically in case of low battery
Dimensions of case: approx. 106 x 67 x 30 mm (H x W x D)(sensor not included)
Weight: approx. 150g (incl. battery)
Electromagnetic compatibility: The device corresponds to the essential protection ratings established in the Directives of
the European Parliament and of the council on the approximation of the laws of the
memberstates relating to the electromagnetic compatibility (2004/108/EC).
Operating Manual for Digital Quick-Response Thermometer
GTH 1150C
Points to be observed during operation
1. As soon as „BAT“ is displayed the battery is used up and needs to be replaced immediately as too low operating voltage
may result in incorrect measurements. Unless the battery is replaced immediately the voltage will not even be enough to
display “BAT”. Therefore, make it a rule to always check the battery – even if no ‘BAT’ warning is displayed – if measuring
results are incorrect.
2. Make sure to maintain device properly and to operate it in accordance with the specification listed (do not throw, knock etc.).
3. Make sure that sensor and device are always subjected to the same temperature, i.e. try to avoid holding sensor plug in
your hand for a longer periode of time as well as subjecting device to an additional heat source as this may result in
measuring inaccuracies.
4. The length of the measuring sensor GTF300 can be reduced as desired so that it will be fully operational again after
sensor has been broken. To do so, please strip both wire ends for approx. 10mm and twist well. Measurements are not
possible as long as wire ends are exposed.
5. The battery has to be taken out, when storing device above 50°C.
It is recommended to take the battery out, when storing device for a longer period of time
General:
The GTH1150C are digital pocket thermometers for quick response temperature measurements.
Depending on the used measuring probe measurements on surfaces, in liquids, soft media, air/gases, at smallest objekts,
etc. are possible.
