The HI98108 pHep®+ Pocket pH Tester is a compact, high-accuracy instrument designed for quick and reliable pH measurements in laboratory, industrial, and field applications. With its slim, ergonomic design and lightweight body, it easily fits in your pocket, making it ideal for on-the-go testing.
This tester features a large, easy-to-read display and simple two-button operation, allowing users to perform measurements effortlessly. The exposed temperature sensor ensures Automatic Temperature Compensation (ATC) from 0 to 50°C, delivering accurate pH readings even when temperature conditions vary.
The HI98108 is equipped with a durable electrode featuring a cloth junction, providing a larger contact surface compared to standard ceramic junctions. This improves measurement stability and extends electrode life, especially in challenging samples.
With a pH measurement range of 0.00 to 14.00 and ±0.2 pH accuracy, the tester supports automatic calibration at one, two, or three points using standard buffer solutions. The device also includes adjustable auto shut-off settings (8 minutes, 60 minutes, or disabled) to extend battery life, which can last up to 1000 hours using a CR2032 battery.
Designed for reliability in harsh environments, the HI98108 operates efficiently in temperatures from 0 to 50°C and up to 100% relative humidity, making it suitable for a wide range of applications.
