Brass and Stainless Steel wetted parts for measuring non-corrosive liquid and gas pressure. Such as water, oil, air pressure test. Compatible with air conditioning line repair, tank, hvac tools, air pump, pipe, tube vacuum test and etc..
Circular dial is enclosed in a 304 stainless steel case for corrosion resistance. Liquid filled inhibits pointer flutter and prevents damage to the internal mechanics from vibration and pulsation.
Freeze Resistant: Silicone oil ensures long-term work in low temperature(-40~140℉/-40~60℃) and suits for most outdoor conditions and seasons.
Measures pressure with dual scale (-30-0 inHg/-100-0 kPa). Display accuracy is + or - 3/2/3% over the entire range of the gauge.
IP67 waterproof prevent condensation inside caused fogging of the window. Offer clear reading.
