Choice of scales, temperatures, operating modes and GLP are at your fingertips with the PTR 46 series. Versatility is the main feature of the PTR 46 and 46X models. The 46 button keypad, with dedicated function and alpha-numeric keys in the standard "Qwerty" layout, gives easy access to the many programmable features of these models.

Available for the sugar industry is the PTR 46X, which measures apparent sugar purity when connected to an Optical Activity Polarimeter.

A simple key press gives access to up to 14 scales; refractive index (RI), Brix (% of sucrose), temperature corrected Brix, temperature corrected RI, and up to 10 user programmable scales. You also have a choice of measuring modes: in Continuous mode, the PTR reads all the time and samples can be read in the same way as the PTR 2 model. Single Scan mode allows you to program the instrument to wait a pre-set time to allow for stabilization and then to scan, display, and hold the result. By selecting AutoPrint mode, the operator can set a time interval for automatic print-outs to monitor a changing or flowing sample. In Stability mode the automatic measuring system within the instrument intelligently decides when the sample has come to a stable reading, and only then outputs the result. The operator can set the level of stability to ensure that the accuracy required is obtained time after time, in the shortest possible time.

The "Qwerty" format keypad on the PTR 46 series makes entering "GLP" (Good Laboratory Practice) data, straightforward. Time, date, and instrument serial number can be output to a printer or computer along with every reading, and the instrument can also be set up to ask for a number, or up to 6 other parameters specified by the user, to fully identify the sample. The titles of these parameters can have up to 20 characters (letters, numbers, or spaces) and can be in any language.

The PTR 46 DL is the latest instrument design.
