The AcuPro Infrared Gas Analyzers are designed for precise lower flammable limit (LFL/LEL) monitoring in clean, low temperature settings. With robust features like a heated optical cell, multiple relay functions, and a Modbus Protocol for digital output, these analyzers provide accurate gas concentration measurements. The NDIR detector ensures stability and accuracy, while the failsafe operation guarantees continuous monitoring reliability. Ideal for institutional and government procurement due to its explosion-proof design and compliance with industry standards.

Product Specifications
Assembly Design Assembly Design
The AcuPro® is an industrial strength analyzer with a complete sampling system, heated optical cell, and integrated controller for continuous measurement of flammable, and some combustible vapors, from 0% to 100% of the Lower Flammable Limit (%LFL, or LEL). It is suitable for monitoring a single solvent in a wide variety of processes. And it may be used for mixtures of solvents with a reduced level of accuracy in processes where the normal solvent concentrations are below 25%LFL.

Failsafe Operation Failsafe Operation
A fault relay de-energizes whenever any of the following occur: controller electrical failure; loss of system power; loss of IR source and loss of flow.
Note Note
As a result of our commitment to product improvement, specifications are subject to change without notice.
Outputs Outputs
The system includes six relays: single-pole, double throw relays for Warning, Danger, Fault; and single-pole, single-throw relays for Horn, Calibration-in-Progress and Service Needed. Other standard outputs include a 4-20mA analog output and an RS-485 serial port with Modbus protocol. Digital remote access and control is available.
Performance Performance
The response time is less than 4 seconds. The analyzer exhibits a very stable zero: less than one percent drift in thirty days. Calibration accuracy has less than five percent error per year. AcuPro® is immune to poisoning and does not require oxygen for operation.

Sampling System Sampling System
An integrated sampling system extracts a sample from the process using a built-in aspirator that develops suction from compressed air. This method is simple, has no moving parts and requires very little maintenance.Infrared energy is passed through the sample, and the amount of infrared energy that is absorbed determines the concentration of solvent vapors. Multiple infrared detectors at select wavelengths help convert concentration data into %LFL flammability readings with greater accuracy for a wider range of solvent types.Autocalibration solenoids, which allow remote activation of calibration tests, are standard.
Sensor Design Sensor Design
The analyzer's non-dispersive infrared detector (NDIR) has a unique heated, multiple-wavelength, mirrorless design. Heating to 60ºC prevents errors from process temperature changes, prevents condensation of water vapor, and maintains accuracy for solvents with Flash Points up to 60ºC. A multiple wavelength detector reduces variation in reading for different solvent types. And the mirrorless design simplifies maintenance by reducing the effects of contamination on the optical cell.
