Laser Moisture Meter Model 4010BR

Laser type! Responds quickly to concentration changes! The world's smallest installed TDLAS moisture meter.

★This model has been discontinued. The successor model is the Model4010LX.★ ● The world's smallest compact wavelength-variable diode laser moisture meter ● Explosion-proof class Class I, Div I, Group B, C, D ● Equipped with data logger and sampling system ● Measurement at PPM levels ● Measurement time is within just 2 seconds (90% response) ■ The Model4010BR is suitable for moisture measurement under conditions requiring explosion-proof functionality, primarily in natural gas and petrochemical applications. Gas molecules such as saturated water vapor, oxygen, and hydrogen contained in process gas have the property of absorbing near-infrared light. The wavelength range at which gas molecules absorb near-infrared light varies depending on the type of gas, and by precisely measuring the wavelength range absorbed by saturated water vapor using TDLAS, it is possible to accurately measure the amount of saturated water vapor without being affected by other gas molecules. Additionally, we have re-evaluated the design concerning the issues of high cost and the need for large installation space that were problems with conventional laser absorption spectroscopy, achieving miniaturization and lower prices. *For more details, please refer to the PDF document or feel free to contact us.*

Fixed-type oxygen concentration meter UOX-B2A

Adopting long-life sensors! This oxygen concentration meter excels in long-term stability with safety as the top priority.

The oxygen concentration meter UOX-B2A outputs the gas concentration detected by the oxygen detection unit JKR-25 as a current signal of 4-20 mA, which is received by the controller COX-B2A, converted into oxygen concentration, and displayed. When the oxygen concentration falls below the alarm set value (factory default 18.0%), the controller activates the ALM1 LED, ALM2 LED, triggers an alarm via a buzzer, and provides alarm contact output and ventilation fan contact output. Adjustment can be made by pressing the span calibration button under normal air conditions. Additionally, during this adjustment, the lifespan of the oxygen sensor is also checked, allowing you to know when to replace the oxygen sensor. 【Features】 ■ Alarm notification possible on the detection unit side ■ Equipped with a high-capacity alarm output (relay non-voltage contact) ■ Alarm output strong action relay contact terminals included *For more details, please refer to the catalog.

Principle of oxygen concentration meters

Principle of Galvanic Battery Type/Zirconia Type Oxygen Concentration Meter

At Tekune Measurement, we handle two types of oxygen concentration meters based on the principles of galvanic cell and zirconia methods. 〇 Galvanic Cell Type The lead anode facilitates the reduction reaction at the cathode by undergoing an oxidation reaction. It behaves as if combustion is occurring at the anode due to oxygen, generating current, which is why it is also referred to as a fuel cell type. PPM models: 2010BX, 2001RS, 2001LC, 1000RS % models: 210BX, Oxtron, 201RS, 1100BE, 201LC 〇 Zirconia Type It compares unknown process gases using known reference gases and the Nernst equation. The electromotive force of the sensor is measured to determine the oxygen concentration. Examples of PPM models: 4100, 7100, etc. Examples of % models: 111, 5100, etc. For more details on the principles of oxygen concentration measurement, please refer to the URL below.
