Description
General Industrial Instrument, General Scientific Instrument เครื่องมือวัด ทั่วไป ในงาน อุตสาหกรรม และ วิทยาศาสตร์ Manometer เครื่องวัดความดันอากาศ Manifold/Pressure Gauge – เครื่องวัดความดันต่าง Differential Pressure Manometer
HD780 : Digital Manifold/Pressure Gauge (500psi) ยี่ห้อ Extech, USA
Dual-Input Heavy-Duty Preassure/Type-K Temperature Meter
Extech’s Heavy duty Digital Manifold/Pressure Gauge simultaneously measures suction line or liquid line pressure and line temperature to calculate and display superheat and sub cooling for A/C units. It also has dual inputs measuring differential pressure (P1-P2) and Type K temperature (T1-T2). For use with R22 and R410A refrigerants. Included are heavy duty connection hoses, Type K Temperature Clamp probe, and bead wire Temperature probe.
Features:
- Dual differential inputs for pressure and temperature
- Displays 5 types of pressure units
- For use with R22 and R410A refrigerants
- Standard 1/4 NPT male flare fittings
- Large backlit LCD displays P1, P2, P1-P2, T1, T2, T1-T2, Ambient Temperature, plus Min/Max/Avg
- Dual Type K inputs with Electronic Offset adjustment to compensate for thermocouple differences
- Large multi-line backlit LCD display
- Data Hold plus Auto power off
- Complete with two heavy duty pressure hoses, protective rubber holster, two Type K temperature clamp probes, two general purpose Type K bead wire temperature probes, Universal AC adaptor with plugs (US, EU, UK, AUS), 9V battery, and hard case
