Thermometers are only part of the system; of equal importance is the design of the temperature probes used to physically measure the item. ETI manufactures an extensive range of type K or T thermocouple probes, PT100 (RTD) probes and thermistor probes to compliment our range of portable, hand held thermometers, data-loggers and instrumentation.
The response time is the time taken for the sensor to reach 66.6 % of the final reading and is the industry standard means of measuring probe response times. Five times the quoted response time is the figure normally required to obtain 100 % of the reading. Response times are dependent upon the substance being measured and, in the case of liquid or gas, upon the degree of agitation. It is therefore difficult to quote an accurate response time without knowledge of the application.
The results given in this catalogue were obtained in a stirred oil bath and may differ from those obtained under other conditions but can be used as a general guide when selecting probes.
Where appropriate, each probe is supplied with a hexagonal, small round, ribbed heavy duty or T-shaped handle. To reduce bacterial growth, probe handles contain 'Biomaster' anti-bacterial additive.
Hexagonal handle manufactured from nylon and available in black. Maximum temperature is 105 °C.
Small Round handle manufactured from nylon and available in black. Maximum temperature is 105 °C.
T-shaped handle manufactured from polypropylene and available in black or white. Maximum temperature is 85 °C.
Ribbed heavy duty handle (with colour coded caps) is manufactured from polypropylene and available in black or white. Maximum temperature is 85 °C.
PVC straight lead is a general purpose lead and available in lengths up to 100 metres. As standard and where appropriate, each probe is supplied with a one metre straight PVC lead and a connector. As an alternative, a one metre coiled PU lead is available for the standard, hand held, type K or T thermocouple probes, replace the first digit (1) of the order code with the number 3. Maximum temperature for both PVC and PU is 80 °C.
Applications quoted are typical for the specific probe, although there are many alternative uses for which the probe could be equally suitable. For advice on a specific probe for a particular application, please contact the ETI technical sales team. Where requirements cannot be met from the existing standard range of probes, alternative designs can be manufactured.
