Simple to Use. Built for Accurate Calibration.

01

Attach Regulator

Secure the regulator to the calibration gas cylinder valve, making sure the connection is tight and leak-free.

02

Set Flow

For fixed-flow regulators, confirm the required flow rate. For variable models, adjust the knob to the desired flow within range.

03

Begin Calibration

Connect the regulator outlet to your detector or sampling equipment, start gas flow, and proceed with calibration.

Frequently Asked Questions

It's used to deliver calibration gas at a steady, controlled rate for field and laboratory calibration of gas detection instruments.
Fixed flow regulators (GV-100, GV-110) deliver gas at one set rate, while variable flow models (GV-200, GV-210) let you adjust the flow rate within a specified range.
Flow rates range from 0.5 L/min on the fixed GV-100 up to 0.2–2.5 L/min on the variable GV-210, covering a wide range of calibration needs.
It's designed to fit standard disposable calibration gas cylinders, making it easy to set up without needing special adapters.
No. It's built for simple, secure attachment and flow setting, making it easy to use in both field and lab settings without specialized training.
