The "CLF-1610 model" is a reagent-free free chlorine meter primarily used for measuring water purification, water supply, and distribution in the online process of drinking water treatment. Chlorine treatment is performed to suppress the growth of fungi and algae in the water supply, and this product continuously measures the residual free chlorine concentration. In addition to an analog output signal of DC 4-20mA, it comes standard with a digital signal RS-485. It can support a new digital instrumentation system using Modbus communication. 【Features】 ■ The detector uses a contactless swing rotary polarographic electrode with a proven track record. ■ Thanks to a unique ceramic bead cleaning and rotational speed control method, it has minimal influence from flow variations, allowing for stable measurements over long periods. ■ The detection unit is compact and lightweight, enabling piping, wiring, and maintenance operations from the front. ■ In addition to wall-mounted and rack-mounted types, options include an indoor self-supporting frame assembly type and an outdoor cubicle storage type. *For more details, please refer to the PDF document or feel free to contact us.

The "LDO2" is a fluorescent dissolved oxygen meter equipped with blue and red light-emitting diodes (LEDs) inside the detector, which alternately light up to perform measurements. Optical zero adjustment is conducted with the red LED for each measurement, allowing for stable measurements over long periods. The detector does not have an anode or cathode, eliminating the need for electrolyte or membrane replacement, and requires minimal maintenance. Additionally, by combining it with a pulse air jet cleaner (optional), sensitivity degradation due to dirt can be reduced. 【Features】 ■ Almost no interfering substances, and no influence from flow rate ■ Notifications for sensor cap replacement and manual cleaning timing are possible ■ The sc200 converter can connect two detectors (optional), enabling measurements with two of the same detector or combinations with other detectors ■ With the sc1000 converter, depending on the type, 4 to 8 detectors can be connected *For more details, please refer to the PDF document or feel free to contact us.

The "WBM-160 model" we handle is a robust, aluminum die-cast, 4-wire (AC-free power supply) field-mounted electrical conductivity meter (2-electrode type) converter. By selecting from four types of reference cell constants, it can accommodate a wide measurement range from ultra-pure water to factory wastewater. It is equipped with a transmission output of DC 4-20mA for electrical conductivity values and water temperature, as well as a two-point adjustment (upper and lower limit alarm c contact) output. Without opening the door, operations such as setting changes can be performed using the waterproof sheet keys on the front, and after two hours in maintenance mode, it automatically returns to measurement mode. 【Features】 ■ Within the specified measurement range, the transmission output DC 4-20mA can be arbitrarily set with a width of over 25%. ■ It measures and displays the temperature of the sample water while outputting the transmission output DC 4-20mA. ■ Measurement values can be adjusted to match known electrical conductivity values. ■ After two hours in maintenance mode, it automatically returns to measurement mode. *For more details, please refer to the PDF document or feel free to contact us.

The "HBM-160B/162B model" we handle is a robust aluminum die-cast, 4-wire (AC-free power supply) field-mounted pH/ORP meter converter. It is equipped with a transmission output of DC 4-20mA and a two-point adjustment (upper and lower limit alarm c contact) output, allowing all operations, including calibration, to be performed using the ten waterproof sheet keys on the front without opening the door. Standard liquid calibration (check) features one-touch automatic stability determination, enabling stable calibration without individual differences, and automatically determines the quality of the electrode characteristics and displays a message. 【Features】 ■ Robust aluminum die-cast construction ■ Equipped with transmission outputs for pH/ORP values and water temperature of DC 4-20mA, as well as two-point adjustment output ■ All operations, including calibration, can be performed using the ten waterproof sheet keys on the front without opening the door ■ Alarm (adjustment) output features adjustable sensitivity settings for upper and lower limit ON-OFF operation ■ The display unit is backlit *For more details, please refer to the PDF document or feel free to contact us.

The "TUF-1600 model" is a turbidity meter that can be widely used for measuring turbidity in various applications, including the measurement of turbidity in process water during drinking water treatment, treated water from sewage and drainage, as well as environmental water measurements in rivers and lakes. The measurement method is based on surface scattering light, where the light source and receiving part do not come into contact with the sample water, preventing any influence from dirt on the cell window, allowing for stable measurements over a long period. 【Features】 ■ Available in single-range, dual-range, and triple-range specifications ■ Uses long-life LED (white) as the light source ■ Sample water flow rate is half that of conventional models ■ Compatible with Modbus communication systems ■ Supports a variety of installation methods *For more details, please download the PDF or contact us.
