This product has been specifically engineered for testing and calibrating Photo-Ionization Detection (PID) devices. It can continuously generate Volatile Organic Compound (VOC) equivalent to isobutylene at a desired concentration.

The essential components of the PID calibrator include:
- a diffusion tube comprising a vial containing chemical standards.
- a dilution chamber that houses the diffusion tube.
- a flow control system with ambient temperature display.

The output gas is isobutylene equivalent, with its concentration primarily determined by the diffusion tube, the adjustable flow rate through the gas flow meter, and the current ambient temperature displayed on the temperature indicator.
Each diffusion tube supplied with this product, whether shipped individually or as part of the package, is designed for a specific isobutylene equivalent concentration and is highly consistent.
Each PID calibrator is accompanied by a unique chart indicating the required flow rate at the current ambient temperature for the calibrator to produce the specified isobutylene equivalent gas concentration. Due to the inconsistency of the gas flow meter, each PID calibrator must be used with its own chart, which is created based on extensive test data in the factory
