two AA batteries.
A versatile and economic choice for a wide variety of pressure measurement applications. Gauges feature easy-to-use, three-button keypad programming. Cycle life of 108 makes these gauges a great value.
Case material is made of PC/ABS. Gauges feature tare, min/max memory, and nine engineering plus one custom engineering units, as well as a bright backlight. Sensor is welded to the socket for added durability. Max pressure indication reduces chances of damage to the unit. Burst pressure rating is 300 to 800% of range. Gauges meet ASME B40.7 safety requirement. Other pressure connections, such as 1/8" NPT(M), are available. Call for assistance.

Q:Does the display for this gauge stay permanantly on or does it go into a standby mode after a few minutes?
A:The gauge will stay on until the power is interrupted.
Q:Can this gauge be used with a diaphragm? If so, please recommend a model. I plan to check the vacuum inside cans and jars of canned foods and want to protect the gauge from the acid and salt of the brine.
A:Hello, I have received your request and will respond shortly.
Q:Could you tell me what sort of sensor technology this product uses?
A:This line of pressure gauges does not use a pirani sensor. They are made specifically with a button sensor.
Q:Will this gauge read inches H20? Another words if I hook up a vacuum cleaner to this gauge will it tell me how much vacuum it pulls (in H20)?
A:This gauge does not offer inches H2O as a scale it can display; inches or mm of Hg are available and a common scale for vacuum. 1" HG is equal to 13.6" H2O, so unless you are using the gauge with a high-power commercial vacuum then most digital gauges will have too great a range for your purposes. I suggest you consider a Magnehelic analog dial gauge depending on your anticipated vacuum range; these are inexpensive, available in ranges as low as 1/4" WC (water column) up to 150" WC and widely used in the HVAC business.
