This is the microprocessor meter that simplifies electrode analyses, Here's how:
The operating mode now selected gives you ion or dissolved gas concentrations directly by the standard calibration method. Other modes let you read millivolts, pH, or concentrations by the various incremental methods without the complication of having to enter analate and standard solution volumes.
The concentration of your standardizing solution (or buffer) is entered in the unit system of your choice. The digital switches let you see what value has been selected at all times.
The electrode slope value is entered (and adjusted as required) on these digital switches. Whenever you use the 901, you can see at a glance if your analytical parameters are correctly entered - without the complicated recall procedures of other microprocessor meters.
You standardize the 901 at the push of a b u t t o n - a n d you're reading concentrations directly on the LED display. Ifyou'd like to see for yourself how simple it is to analyze your samples with ORION electrodes and the 901, call ourtoll-free number and we'll arrange foroneofourtechnical specialists to set up a full-fledged demonstration in your laboratory.
