Until now, when measuring with large equipment, there were challenges with exhaust gas analysis instruments, such as customizing measurements in-house to display values on a separate monitor or repeatedly going to check and adjust measurement results. The portable combustion exhaust gas analyzer HODAKATEST "HT-2900" allows remote operation of all functions via a remote control, measures O2 as standard, and lets you freely select other necessary gases. This product contributes to reducing work time and personnel. 【Features】 ■ CO sensor with H2 compensation (* H2 compensation is a correction to prevent errors when measuring gases containing H2.) ■ Capable of analyzing up to 8 gas components with a single unit! ■ The measurement principle combines potentiometric electrolysis and infrared methods, using infrared measurement for CO2, CH4, and C3H8! ■ Equipped with a high-speed thermal printer as standard! ■ Can incorporate a full-fledged gas pre-treatment device inside the main unit! (Optional) ■ Quick response for after-sales support! * For details, please download the catalog or contact us directly.

Starting from April next year, the inspection standard for the "combustion state of gas appliances" mandates that the carbon monoxide concentration in the combustion state of gas instantaneous water heaters must be 0.2% or lower. The Hodaka Test HT-1210N is an analyzer that complies with this standard.

With a chimney height of 100m, a draft of about 4 hPa will occur at the boiler outlet. In this case, it is necessary to pay attention to the following points: (1) Whether there is sufficient exhaust gas suction power at the required exhaust gas flow rate for combustion analysis. (2) If it is anticipated that the exhaust gas suction power will be insufficient, consider adopting an exhaust gas sampler as an option. (3) Carefully check for any gaps in the boiler's smoke chamber door and flue connection flange. If there are gaps, air may leak in through those gaps, potentially preventing accurate combustion exhaust gas analysis. ● For more details, please download the catalog or contact us.

If low pH drain accumulates on the metal parts or sensors of the combustion analyzer, corrosion may occur, which could prevent the combustion analyzer from functioning properly. As a countermeasure, drain pots and other devices are installed on the inlet side of the combustion analyzer to prevent drain from flowing in. In practice, when the combustion analyzer is used for an extended period, a significant amount of drain may accumulate in the drain pot. It is advisable to always ensure that drain does not flow into the combustion analyzer. ● For more details, please download the catalog or contact us.

The actual air ratio of the boiler can be calculated based on the exhaust gas oxygen concentration (O2 %) measured by a combustion gas analyzer. Below, we will describe the basic concepts regarding the air ratio and its calculation formula. The theoretically required amount of air calculated from the fuel composition is called the theoretical air amount. However, in practice, it is difficult to achieve complete combustion with only this theoretical air amount, so a little excess air is actually supplied to the burner. This actual amount of air is referred to as the actual air amount. The air ratio is defined as the value obtained by dividing the actual air amount by the theoretical air amount. As the air ratio increases, the amount of exhaust gas increases proportionally, leading to an increase in exhaust gas losses. Therefore, the Energy Conservation Act specifies the standard air ratio as follows. ● For more details, please download the catalog or contact us.

It is necessary to adjust the burner to achieve the appropriate wind pressure and gas pressure. By using the pressure switch (HT-1100), you can quickly measure the pressure at five locations with a single digital manometer. 1) Wind box wind pressure 2) Furnace pressure 3) Flue draft 4) Primary gas pressure of the burner 5) Secondary gas pressure of the burner Connect these pressure measurement points to the secondary side shown in the left diagram using a tube, and sequentially switch the rotary knob to measure the pressure at each part. ● For more details, please download the catalog or contact us.
