The HH311 is a low cost, high performance handheld meter. It offers a triple display to show the temperature and humidity from a handheld probe and can display data from a separate K type thermocouple connected via a standard SMP type miniature connector to the T2 input. The temperature/humidity probe uses a semiconductor and polymer capacitive sensor. An optional software package is offered to allow data to be read by a PC through the RS232 port.

Rated 5 out of 5 by from Well designed and packaged I purchased this last week and am very satisfied that I did. Works well. Easy to use. It appears that the reading is accurate. The unit came with a RS232 connector for data logging. Software included.

Does the HH311 come with a traceable NIST certificate?  Not just a generic postcard saying it’s traceable to nist. If not how can I add a level cal-3 to this item? It should be an option displayed at checkout?

Asked by: RVLH
The NIST Certificate that is sent out with the meter is the postcard version you describe. In order to get the full NIST Certificate you would use part number HH311-CAL-3 which you can enter and add to the cart if ordering on line.

Is this a calibrated device and does it come with a certificate of calibration? If it has a cert how long is the cert good for?

Asked by: Izzy
Thank you for your inquiry. This model is fully calibrated and is supplied with a NIST certificate valid for one year.
