Formic Acid Gas Detector

$2,170.00

Product Summary

PureAire’s Formic Acid Gas Detector provides continuous, real-time monitoring of formic acid (HCOOH) vapors in industrial environments where safety, compliance, and process control are critical. Designed with a dedicated electrochemical sensor calibrated in parts-per-million (ppm), this detector ensures accurate leak detection and rapid response to hazardous concentrations.

Formic acid is widely used in industries such as leather tanning, textile dyeing, rubber production, pharmaceuticals, and as a preservative in livestock feed. It also serves as a key chemical in manufacturing processes and cleaning agents, especially in semiconductor and laboratory environments.

Formic acid is highly corrosive and toxic, capable of causing severe skin and respiratory irritation upon exposure, especially in enclosed or poorly ventilated spaces. Continuous gas detection is essential to protect workers, prevent equipment corrosion, and maintain regulatory compliance.

PureAire’s Formic Acid Gas Detector offers a durable, low-maintenance solution with sensors lasting up to 8 years in standard operating conditions. On-site rechargeable sensors minimize downtime and reduce long-term costs, making them an ideal choice for facilities requiring reliable, high-performance formic acid monitoring.

Please note that because of the nature of this product, the lead time is typically 2-3 days but may be up to one week. We will make every effort to ship your order as soon as possible.

The PureAire Formic Acid Gas Detector is a compact fixed gas monitor that’s ideal for protecting workers from toxic and corrosive gas exposure in the workplace. It consists of a transmitter/controller connected to a dedicated, renewable, formic acid gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Formic Acid Gas Detector can also be connected to any programmable logic controller or SCADA system. PureAire also manufactures toxic gas detectors with a remote sensor.

The heart of the Formic Acid Gas Detector is the smart, renewable sensor cell programmed with gas and measurement range information. When servicing the sensors, they can be recharged with fresh electrolyte and dynamically gas-calibrated in the maintenance shop away from the transmitter.

Affordable, Low-Cost Operation

PureAire’s Formic Acid Gas Detector stands out with the lowest annual maintenance costs in the industry. Thanks to PureAire’s renewable sensors, you can easily recharge the sensors with electrolyte in the field, costing you just 20% of what you’d spend on disposable sensor cell systems. With routine maintenance materials averaging $70 per year, this system saves you hundreds of dollars annually compared to the high costs of traditional disposable sensors. The smart choice for long-term savings!

Effortless, Stand-Alone Monitoring

The Formic Acid Gas Detector is designed for simple, stand-alone operation. No complicated setup required—just mount the detector near the risk site and plug it into any standard 115VAC 60 Hz outlet or 220VAC 50 Hz outlet. You’ll be monitoring gas levels in no time! With a built-in horn and LED alarm indicators, the system quickly alerts your team to hazardous conditions. For further flexibility, the individual alarm and fault relays allow for easy connection to remote alarms or control systems, while the 4-20mA analog output provides continuous data to remote PLC and SCADA systems.

Always-On, Intelligent Supervision

The Formic Acid Gas Detector is equipped with smart, 24/7 supervised circuitry. In the unlikely event of a system error, the detector’s analog output and fault relay immediately notify control room personnel, ensuring prompt action. Additionally, the dedicated microcontroller built directly into the sensor makes routine calibration and maintenance a breeze. Calibration data is easily entered into the sensor electronics and transferred to the transmitter once reconnected, ensuring accurate monitoring without the hassle.

Experience peace of mind with reliable, low-maintenance gas detection that keeps your team safe and your operational costs low!
