Features
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.

For the money, the HH311 cant' be beat. They are reliable, repeatable, and accurate.
We have several in our shop and will continue to use them!

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.

could i connect this device with a USB to my PC r just RS 232
Hi Maha12
Thank you for the inquiry. Interface is RS232. Software and cable are sold separately on this model.
Please consider the new HH414 which includes software and USB cable;

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?
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.

Hi, could it be connected with a USB or just RS 2032?
Hi Maha12,
Software and cable are sold separately. There is an adapter cable version which allows connection to Windows 7 64 bit.
HH414 includes software and USB cable

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

Hi, i want to know what 's the range of temperatures and humidities that this device can mesure because I don't know why it's written in the description max and min temperature -200°C
The HH311's wand probe has a measurement range for RH and temperature of -20 to 60C and T2 the Thermocouple input can measure from -200C to 1370C.
