Description
The HI99131 is a professional portable pH meter engineered for plating applications and challenging environments. Its titanium probe construction ensures unbreakable durability while providing fast thermal response via the internal temperature sensor. The gel-filled electrode design eliminates the need for a fill solution, minimizing maintenance. Automatic one- or two-point calibration using standard pH buffers ensures accurate readings across the full pH range (-2.00 to 16.00).
Equipped with Automatic Temperature Compensation (ATC) from -5 to 105°C, the meter corrects pH readings for sample temperature variations automatically. The HI629113 probe connects via a quick-connect DIN connector, and the meter features a Battery Error Prevention System (BEPS) to prevent unreliable readings due to low battery. Compact, lightweight, and waterproof (IP67), the HI99131 comes with all necessary accessories including pH buffers, cleaning solutions, beaker, batteries, calibration certificates, instructions, and a rugged carrying case, making it ready for both lab and field use.
