‘LOBAlife’ Micro controlled pH SYSTEM

Model PH61 is a high performance, Micro controller based pH meter for accurate pH measurements in Chemical, Medical, Research laboratories and wherever a pH measurement is required. The pC pH SYSTEM 361 offers automatic temperature compensation as well as automatic pH standardization for optimum speed and accuracy. For pH electrodes deviating from the standard Nernst slope, necessary slope correction is done automatically. The system reads both pH and temperature, simultaneously, for complete sample information. Besides pH and temperature measurements, the unit can be used for measuring Redox potential in its Real mV mode. It can be also used as general purpose millivoltmeter. Active operating measuring mode (pH, Rel. mV, CAL, Abs. mV) is indicated by LED. In standardization (CAL) mode, it automatically sets the digital read-out to the value of standard buffer (e.g. 7.00 pH and 4.00 pH or 9.2 pH) after automatically compensating for the temperature of the solution. Printer interface is available for hard copy. Standardization remains in memory. One of the prime features of this system is the automatic electrode efficiency check to assure good reading. Moreover, bare minimum controls on front panel and ease of operation make it handy for routine analysis. The unit is housed in a compact and light weight two-tone cabinet.

pH System PH62
‘LOBAlife’ pH System PH62 is an intelligent high resolution and precise instrument. It measures pH of a solution, using a pH electrode. The unit can also measure millivolt (mV) generated by the sensing electrode. It is named as mV-Absolute when the unit is asked to work like a conventional voltmeter and as mV-Relative when the voltage is measured with reference to a 7 pH solution. Facility to measure temperature using a Pt 100 sensor is also provided. The unit offers pH range from 0 to 14.000; mV-absolute up to ± 1999.9 mV; mV-Relative up to ± 1999,9 mV; temperature from 0 to 99.9°C.
