To maintain reliable measurements, we recommend regular calibration of each measuring instrument. Measuring instruments are subject to aging, and any instrument is likely to experience an increase in measurement error over time. It is important to ensure that this error does not affect measurement accuracy. The calibration cycle varies depending on the instrument. For the TK-100 dew point meter, we recommend calibration once a year due to the aging of the ceramic in the measurement section. However, for hygrometers that use artificial, highly stable polymers and PT100 temperature sensors, we recommend calibration every two years for mirror-type dew point meters, which primarily suffer from degradation. For more details on calibration, please refer to the URL below.

Uncertainty is like the sum of factors contributing to error, so naturally, the fewer the factors contributing to error, the smaller the uncertainty will be. In other words, when repeating a "chain of calibrations" to "ensure traceability," the more calibration instances there are, the greater the uncertainty and the lower the reliability. This is because environmental factors, equipment errors, and measurement errors accumulate with each calibration. Generally, it is said that adding one more calibration doubles the uncertainty. Therefore, even when calibrating to ensure traceability, it is better to perform the calibration with equipment as close to national standards as possible. At Tekune Measurement, we possess and sell equipment that is close to national standards. For more details on uncertainty and traceability, please visit the URL below.

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.

We adopt TDLAS. TDLAS stands for Tunable Diode Laser Absorption Spectroscopy, which is also known as wavelength-tunable semiconductor laser absorption spectroscopy. Laser light generated by a semiconductor laser is irradiated into a measurement cell, and the intensity of the laser light that has passed through the measurement cell is measured. This TDLAS allows for a rapid response to changes in moisture concentration and enables accurate monitoring of saturated water vapor levels. Furthermore, the use of dew point meters, which can measure moisture concentration quickly and accurately, is increasing in determining the purchase price of natural gas in Europe and the United States. The measurement range can detect low dew points down to -60 °C dp. For more details on the principles of laser dew point meters, please refer to the URL below.

The principle of the phosphorus pentoxide (electrolytic) moisture analysis is utilized. (1) Phosphoric acid generates phosphorus pentoxide, hydrogen, and oxygen through electrolysis. 4H3PO4 → 2P2O5 + 6H2 + 3O2 (2) Phosphorus pentoxide absorbs water. 2P2O5 → 6H2O + 4H3PO4 The sensor is made of glass, with platinum electrodes (rhodium as an option) wound in a spiral around it. Oxygen is generated between the electrodes. The amount of water absorbed by the generated phosphorus pentoxide is balanced with the amount of hydrogen and oxygen produced, allowing for moisture measurement based on Faraday's law (the amount of substance electrolyzed is proportional to the amount of electric charge passed). It is resistant to corrosion, making it suitable for measuring moisture levels in corrosive gases. Additionally, it is a long-established dew point meter.
