Gas detectors and monitors provide necessary protection from hazardous gases in the workplace. A wide variety of monitoring instruments are available for purchase or lease, including multi-gas or single-gas monitors and portable gas detectors. At All Safety Products, Inc., we provide high quality, economical products that meet OSHA safety regulations and ANSI standards. It is important to recognize that proper maintenance and regular calibration are necessary ingredients to a successful gas detection program.

The most important part of a gas monitor is the sensor or sensors, which must be replaced at regular intervals. Due to the use of sensor technology, the accuracy of monitor readings must be routinely checked or calibrated against a known standard. Calibration techniques vary. Manufacturers have improved the convenience of the calibration process, but routine testing is still required on a monthly or bi-monthly basis.

Recent technology has provided automated management systems. Monitors sit on "docking stations" that produce 24-hour monitoring and reports via the Internet. This service will detect instrument failure, low calibration gas, and sensor problems. Many employers recognize the cost and time saving advantages of using an automated system for gas monitor maintenance and repairs.

Many gas detectors are portable, reliable and easy to use. Some are housed in durable, weatherproof cases. Features may include audible, visible, and vibrating alarm systems, a rechargeable battery, compact size and weight. Monitors are available to detect a single gas or multiple gases such as O2, H2S, CO, and combustible gas. Popular features are a large LCD display, one button calibration, and accessories such as charger, carrying case, and belt clip.
