MSA 711174 Manual Trigger Regulator - Each

Two regulators in one. Trigger activation allows bump test or calibration check in the SQUEEZE mode or fixed-flow calibration in the up or LOCKED position. Designed for use with all Model RP & Econo-Cal Calibration Cylinders. Supplied with calibration tubing & special adapter fitting. Approved for all MSA calibration gases.

• No need to manually open or close a valve for accurate calibration once attached to the calibration cylinder
• No on/off valve is necessary because the regulator automatically turns itself off when not in use, simplifying the test & calibration process & saving calibration gas
