DeltaTRAK Releases New ISFET pH Meters, Model 24300 and 24301

PLEASANTON, CA - (Feb, 18, 2009) - DeltaTRAK®, Inc., a leading innovator of cold chain management solutions and professional food safety products has released two new ISFET pH meters. These unique Ion-Sensitive Field Effect Transistor (ISFET) devices use non-glass probes, making them ideal for laboratory and food science applications. Both models can support a third party glass probe with standard BNC connector, if needed. Model #24300 is a rugged, waterproof, hand held device. Model #24301 is Good Laboratory Practices (GLP) compliant and also features a waterproof casing. Both instruments can measure pH, mV, and temperature.

The model #24300 pH meter is armored in a chemical resistant holster which is engineered to withstand a six foot drop onto concrete. The large LCD display is easy to read, making it an excellent choice for food testing, life sciences, industrial applications, and educational use.

Model #24301 has an extra large backlit LCD display and features Bluetooth data transfer capabilities. Internal memory will store up to 999 data points. PC graphing and data logging software is included. This pH meter can be hand held or used in applications for unattended monitoring. It too is an excellent choice for food and life sciences applications.

There are 2 probe model options available when purchasing these pH meters. Model #24302 is a general purpose, stainless steel probe. Model #24303 is a heavy duty, meat piercing probe, intended for direct pH measurement of beef, pork and other meat products in processing facilities.
