FEATURES
High corrosion resistance and drip-proof construction
Pressure port attachment made of SUS 316L
Proven IP-65 grade gauge body (IP-65 in accordance with IEC)
Standard product provides both a switch output
(hysteresis adjustable) and an analog output
Absolute pressure type and compound pressure type
which can control negative to positive pressure with only
a single pressure gauge are all in line
Three standard types of joint are provided
R2 : R 1/4 (M 5 female screw)
GF : G 3/8 with flash diaphragm
