Portable instruments for chemical processes

April 2004 Analytical Instrumentation & Environmental Monitoring

LTH Electronics, a British-based Company, has developed the HD series of portable pH, redox, conductivity and temperature-sensing instruments. These meters are provided in a choice of instrument packaging, with the 9212 and 9213 in a small, soft carrying case, or the 8705 and 8706 in a sturdy diplomatic case. They are simple to operate and come as complete kits, including a pH or conductivity probe and temperature sensor.

The HD9213 is a portable conductivity meter that can also measure temperatures in the range -25 to +60°C. The accuracy is ±0,5% of full-scale The HD9212 is a portable pH meter that can also measure redox and temperature. It has a temperature measuring range of -50 to +200°C.

The HD8706 is a portable conductivity meter that can also measure temperature. It has the same measuring range as the HD9213, and it has additional functions such as hold, record min, max and relative measurements. It also comes with automatic or manual calibration.

The HD8705 is a portable pH meter that can measure redox and temperature. It features the same measuring range as the HD9212, and the same additional functions as the HD8706. It comes with the option of a RS232C serial output. The HD8706 and HD8705 feature auto ranging, they store min, max and relative readings and offer a wide conductivity measurement range, using the four-electrode conductivity cell. The kit includes calibration standards in the diplomatic carrying case.
