Extech Instruments EXTRH300-CAL Humidity Calibration Kit

Q: Can you use on the 445815

This is the recommended calibration kit for 445815.

Q: I need the instructions, can anyone supply these? I recently bought this through amazon. Can anyone help??

The instructions (from Extech) come with their meters, not the calibration jars. I use these standards with my Extech 445580, and combined, the meter and the calibration jars are effective. The instructions with the 445580 stress that the meter be given lots of time to equalize (40 minutes per jar!). I found it doesn't need quite that long, but definitely requires around 15-20 minutes in order to stabilize and give an accurate reading. Be patient.

Q: Will the hole in the top accommodate a probe that is 3/4" in diameter?

Hello Mika,The opening on the RH300-Cal salt bottles are 0.5". A 0.75" probe will be too large.Best Regards

Q: does it comes with nist certificate?

Hello, Thanks for your question, No, the Kit does not come with a NIST certificate. If you have any questions, please feel free to contact our tech support line at 866-477-3687 option 3
