HI 991401 - pH and Temperature Monitor with Large Backlit LCD

This indicator from Hanna has a large, dual-level back-lit LCD to give you instantaneous readings of both pH and temperature, even from a distance. The microprocessor provides automatic calibration, automatic buffer selection and automatic temperature compensation. The waterproof pH indicator HI 991401 has been designed to meet the grower's need for equipment suited to the aggressive environments found in agricultural and hydroponics applications. Measurements are highly accurate and can be verified with one or two point calibration. Low batteries and battery changes are no longer a problem thanks to a 12 VDC power supply included with the meter.

The electrode is interchangeable and has been specially designed to address the needs of growers. Its design guarantees greater clogging resistance in fertilizer solutions with high concentrations of phosphate, nitrate, etc. This is a major improvement ensuring longer life for your electrode!

HI 981402 - Water Resistant pH indicator with Visual Alarm for Water Treatment

HI 981402 is a water-resistant pH meter with a built-in 31⁄2-digit LCD. The meter is supplied with the HI 1286 double-junction, plastic-body, gel-filled combination pH electrode with a 2 meter (6.6’) cable. The BNC connector is protected by a waterproof sheath. The electrode also has a unique clog resistant Teflon® diaphragm. The alarm setpoint can be selected anywhere in the 3 to 11 pH range. A red LED warns the user in the event the reading is outside the setpoint by more
than ±0.5 pH. Calibration can be manually performed at 1 or 2 points through two easily accessible trimmers on the front of the unit. The meter is suited for outdoor installations and highly humid environments. The casing has been specially designed to give maximum stability and prevent rolling from any surface. In addition, the molded hook allows the meter to be easily installed close to the sample. The 12 VDC power supply is ideal for continuous monitoring over extended periods of time.

HI 981400 - pH Meter and Indicator with Alarm for HACCP and QC

HI 981400 is an indicator designed to check the pH of foodstuffs. The pH value ranks as one of the most important indicators of food quality and safety. pH of raw ingredients such as milk and meat is measured to ensure that quality standards have been properly met. pH is also monitored at different stages of food preparation and processing to guarantee safety, improve
production and enhance quality. Along with temperature and water activity, pH also determines the shelf life of foodstuffs. For example, by bringing the pH value below 4.5, growth and multiplication of pathogens are inhibited. HI 981400 is compact and affordable. It has a large LCD display and comes with a molded eye for hanging. It can be hung at a convenient position above a QC bench, or at the goods-in area. Through a trimmer on the back of the unit, an ideal pH value can be set between 4.0 and 7.5 pH. Should the pH exceed this user-selectable limit, an incorporated LED starts flashing to signal an abnormality. This is an important feature that permits the control of pH to be delegated to operators with less technical skills.
