Product information "Horiba LAQUAtwin Calcium Ion (Ca2+) Tester with 2 calibration points and temperature measurement (Ca-11) "

Mobile Calcium Ion Tester from Horiba with Temperature Measurement – precise, compact, robust

Handheld Ca²⁺ pocket tester with 2-point calibration and temperature display – ideal for water and environmental applications

The mobile Horiba LAQUAtwin calcium ion tester measures both the Ca²⁺ concentration and the temperature of a sample. Equipped with an ion-selective sensor, a digital LCD display, and a minimal sample volume of only 0.3 ml (0.05 ml when using the sampling sheet), it delivers fast and reliable measurement results. Thanks to the integrated temperature display and automatic temperature compensation, calcium values can be measured accurately even under changing environmental conditions – making the device ideal for mobile applications.

Mobile calcium ion tester for precise on-site measurements

With two calibration points and automatic standard recognition (150 and 2000 ppm), the device can be flexibly adapted to different measurement situations. Temperature-compensated measurement, multiplicative compensation, automatic stability and hold modes, as well as automatic shut-off ensure easy and reliable operation.

The tester is dustproof and waterproof according to IP67 and offers a long battery life of approximately 400 hours. It is supplied complete with standard solutions, sampling sheets, pipette, and batteries.

Why calcium measurement is important – optimal results with the Horiba handheld tester

Calcium is a key parameter in water, environmental, aquaculture, and food analysis. Calcium concentration influences water hardness, biological processes, coral growth, and product quality in beverages and food. Deviations can lead to ecological, technical, or quality-related impacts.

A mobile calcium handheld tester allows fast analysis directly at the point of use without complex laboratory procedures. This makes it possible to detect changes immediately and take timely action. The Horiba LAQUAtwin calcium tester combines this flexibility with high measurement accuracy, simple operation, and a robust design.

The HORIBA LAQUAtwin Pocket Tester series provides a comprehensive solution for immediate and precise measurement of water quality parameters directly in the field. To ensure these measurements remain reliable and accurate, regular monitoring of the sensors and, if necessary, replacement with spare sensors is essential. The replacement sensors are specifically designed for the HORIBA LAQUAtwin series and cover a wide range of types for various measurements: pH, conductivity, salinity, redox (ORP), as well as ion-selective sensors for sodium, potassium, nitrate, calcium, and fluoride. Each sensor is engineered to maximize user-friendliness and accuracy, qualities for which HORIBA is globally recognized in water quality testing. HORIBA replacement sensors ensure that users’ devices consistently deliver optimal performance and precise measurements. Advantages of HORIBA Replacement Sensors: Easy Replacement: The sensors can be replaced quickly, allowing measurements to continue without delay. High Precision: Replacement sensors ensure that results are accurate and reliable. Wide Measurement Range: Various sensor types are available to cover a broad spectrum of water quality parameters. Durability: The sensors are designed for long service life, even under challenging conditions. Sensor Replacement Instructions: Follow these steps when replacing the sensor to ensure the longevity and accuracy of your HORIBA LAQUAtwin Pocket Tester: Removing the Sensor: Turn off the tester. Lift the sensor tip slightly and pull the sensor a short distance away from the device. Completely detach the sensor from the tester. Installing the Sensor: Ensure the tester is turned off. Check that the waterproof gasket is intact and clean. Place the sensor onto the tester so that hook “A” on the back of the device fits into hole “a” on the sensor tip. Make sure the waterproof gasket is not twisted. Important: After replacing the sensor, follow the instructions in the user manual of the respective tester to make the device ready for accurate measurement. These manuals are available with the products and typically require calibration and, if necessary, conditioning. How can I tell if my sensor is worn out? Check the sensor condition as follows: Perform a 2-point calibration. If an error occurs during calibration, this indicates that the sensor has deteriorated. In this case, the sensor should be replaced. Regular checks and timely sensor replacement ensure that water quality measurements with HORIBA LAQUAtwin Pocket Testers remain accurate and reliable.
