How does soil temperature affect the accuracy of the result?

Asked by: Rob1
Thanks for your question. The operating temperature for this model is 0° to 50°C. Outside of this temperature range, the meter may no longer read properly (or at all) and the accuracy rating no longer applies. Please contact our Tech Support if you have any further questions for your application.

What is the operating principle for this meter? Is it robust to salinity in the soil? I need to measure soil moisture along the coast.

Asked by: Zoya
The probe would be able to measure the moisture in most soil types and if there is salinity involved it is recommended to clean the probe after each use as to avoid the initiation of corrosion.

I got the probe but the value jumps from 2 to 40, I stayed more than a minute and the reading didn't got stable. 1. How long should I stay to get it stable? I know my range must be between 35% and 40% 2.Does the reading depends on the sample size?

Asked by: Gustavo
Thank you for your question? This probe only works with soil or other similar material. Hope this was helpful?

My HSM50 moisture meter is not powering on and is out of warranty. I replaced the batteries, but no joy. Is there anything that I should be checking? Are repairs available?

Asked by: GregRSF

Does the product work well in agricultural settings to measure soil moisture under pivot irrigation?

Asked by: pivot
The probe is the only portion that should be exposed to direct moisture. The display area which holds the electronics should not be exposed to direct irrigation water spray.

Would this handheld moisture meter work to detect moisture in powders?

Asked by: Ricky123
Very dry soil can have the consistency of powder so the HSM50 should allow a relative measurement of moisture in powder if it is similar.
