Omega’s HHP360 is a very high accuracy, handheld barometer/ absolute pressure meter suitable for the most demanding field or laboratory conditions. It can measure absolute pressure, barometric pressure (corrected to sea level) or altitude based upon sea level or corrected for a map or trig marker. Pressure can be displayed in 1 of 7 different engineering units. Altitude can be displayed in either meters or feet. The HHP360 Series also has a leak test mode to determine the rate of leakage in a pneumatic system, and data logging, either automatic (taking readings every 5 seconds for 20 minutes) or manual for up to 240 readings.

Poorly built chassis, but decent manometerI had to rewire the battery terminals after receiving a brand new unit, the terminals fell into the chassis and i had to take it apart to get them out and remount them - after i was able to get it powered, it seems to be OK - i hope the batteries last a while.
Yes, A Certificate of Conformance is sent automatically with the Order Confirmation when you place an order. The NIST cert is shipped with the unit

I have a unit HHP360A, that turs on and will not power off if the power button is pressed down after use and vice versa. The only way to rectify the issue is to pull out the batteries each and every time. Possible causes? Batteries are new.

Thank you for your inquiry! This is an unusual occurrence. As long as you are in Measure Mode the unit should turn off when the on/off key is pressed. Please contact us at firstname.lastname@example.org so that we can further troubleshoot the unit.

What is the recommended calibration interval for this unit? Any statement letter that you can provide?
Asked by: lenovski
Generally on all our pressure products the supplied NIST certification is valid for one year from the date the unit ships out to you. This is usually stated on the calibration certificate.
