Model 1409 SOLFRUNT Test Gauges are stem or low mount pressure gauges used for field testing and validation, with an ASME B40.100 Grade 2A accuracy (±0.50%) up to 1000 psi, or Grade 1A ((±1%) for 1500 psi and above. The Model 1409 has a light weight chrome plated ABS solid front case with a blow out back design. This pressure gauge has a knife-edged micro-adjustable pointer to reduce parallax readings.
