Product Details

GTI Micro Differential Pressure Gauge GTI135/145 Biosafety CabinetTwo compact micro differential pressure digital displays with high voltage resistant micro silicon resistance sensors and advanced digital technology are used to achieve highly sensitive and reliable differential pressure testing. Easy to install, segment code LCD display, clear and accurate readings, with analog output and switch functions.

The GTI ultra small micro differential pressure digital display meter is widely used in HVAC, food, biopharmaceuticals, aerospace engineering, intelligent buildings, environmental monitoring, precision electronic manufacturing and other fields to achieve pressure testing of fans, fans, filter resistance, furnace pressure, orifice plate pressure difference, and combustion system pressure difference. It is an ideal choice for embedded pressure difference testing of equipment such as cleanrooms, biosafety cabinets, and negative pressure vehicles.

Features

Choose one of multiple differential pressure ranges and display the segment code on LCD;

Switching function (dual NPN or PNP collector open circuit output);

Analog output of 1-5VDC or 40-20mA, can also be specially customized;

Differential pressure display, analog output, digital filtering, button locking, peak and valley value retention display, and zero point adjustment;

Easy to install, with two installation options available: wall mounted or bracket mounted;

Two sizes, 30x30mm and 24x48mm, meet different options;
