Therma-Hygrometer with max/min & alarm functions

  • Range of -49.9 to 69.9 °C & 20 to 99 %rh
  • Integral %rh & remote temperature probe
  • Temperature alarm feature
  • Probe length 3m 

This therma-hygrometer simultaneously displays both the humidity and temperature in addition to indicating and recording the maximum and minimum readings.

 

Product code:
810-155

The therma-hygrometer measures both humidity and temperature over the range of 0 to 49.9°C and 20 to 99%rh utilising the internal sensors. Utilising the external temperature sensor the temperature range is extended to -49.9 to 69.9°C.

The therma-hygrometer features a temperature alert alarm that will sound when the external remote temperature probe indicates the temperature is 0°C or below. This feature is ideal for frost/freeze alert in horticulture and similar.

The therma-hygrometer is housed in an ABS case measuring 20 x 65 x 97mm, the case incorporates a useful foldaway stand and a keyhole slot for hanging on a wall.

Very useful

Compact but easy to read, very clear display. Very easy to set up, you just have to pull out the insulator tab by the battery. Seems to be accurate for both temperature and %RH. Having the min/max memory function and outdoor sensor are very useful for use in a greenhouse (which is where mine is). Haven't yet had temperatures to trigger the alarm function.

Neat little device

This is a well designed device and comes with plenty of options for mounting the unit and the remote sensor. I have compared it with other thermometers and the temperature seems very accurate, but I have no means of testing the humidity readings. Overall I am very pleased with it.

Quality product and quick delivery

About the size of a pack of playing cards, which is ideal. Thermometer is slightly slow to read, but the hygrometer is fairly quick which is what I wanted it for.

Instrument arrived safely and quickly.

Instrument arrived safely and quickly. It has a good response to changes in humidity and temperature and seems quite accurate. I would happily use this company again and I appreciate the catalogue of its products which was included in the package.

Great product, I was looking

Great product, I was looking for accurate instruments to measure temperature, & these solved the task in hand perfectly. I had used some cheap Chinese units prior to purchasing yours. The ETI units clearly showed just how inaccurate those cheap ones are. Coming from a company who specialise in temperature measuring instruments, I trusted ETI to deliver what was required, & they certainly did not disappoint in the least. Very pleased with these accurate units, thank you.

Excellent and reliable. My first

Excellent and reliable. My first one was purchased in 2015 and this is my third. Apart from room temperatures they have also doubled as fridge and freezer checkers when required, by using the external probes.

Seem quite good but don’t

Seem quite good but don’t know how accurate it’s reading is, but gives me an idea of the temperature so I am happy with it so far. Hope to test it when someone who has temp readings in their car comes to visit! Prompt delivery .

I bought the Therma-Hygrometer after

I bought the Therma-Hygrometer after my old one failed to recover from recent thunderstorms (should I disconnect the outdoor sensor?). Indoor and outdoor measurements agreed closely and were in line with other instruments. The miniature jack-plug is known to be a source of occasional false readings and might improve with gold plating.
