Measurement with application of 4 load cells is a guarantee of precise mass reading, regardless of l (more)oad positioning on the weighing platform. The platform scales C315.4 series is made of mild steel powder coated construction of the weighing platform. The platform comprises 4 load cells connected to an terminal PUE C315 series featuring backlit LCD display and 5 function buttons. The weighing platform and the terminal are connected through a long cable enabling hanging the terminal on a wall. The C315.4 series is available in pit version for easy placing heavy loads on the weighing platform without application of ramps. Scales is available in dual range version on surcharge.

The AP-12.5Y is designed to calibrate multichannel pipettes starting at 10 μl. The device feature (more)s a readability [d] of 0.01 mg and can calibrate up to 12-channel fixed-volume and variable-volume pipettes. Because the pipette calibration on the AP-12.5Y is fully automatic, it is four times faster. The calibration procedure for a 12-channel pipette takes less than 20 minutes, not six hours, on this instrument. When purchasing the AP-12.5Y, you get: two calibrated sensors: THB S and THB W, two weighing pans: standard, and for balance test and calibration, two pumps: a single-channel pump and a four-channel pump The ergonomic design of the AP-12.5Y makes it possible to empty weighing vessels, and their overfilling is signalled by Ambient Light. When calibrating a multichannel pipette, a four-channel pump is used to simultaneously remove water from four vessels, greatly reducing the time required for pipette calibration. After emptying a 12-channel pipette, the AP-12.5Y checks all channels in a single cycle. In addition to a database of pipette calibration reports, the AP-12.5Y includes a database of pipettes that is editable and contains maximum permissible error values according to ISO 8655. The report database, in turn, contains measurements and error values calculated for individual points and volumes. The user determines the format and content of the reports. The AP-12.5Y monitors the ambient conditions using calibrated sensors: THB S (ambient conditions measurement) and THB W (liquid temperature measurement), in accordance with ISO 8655. To calibrate the device with mass standards, the weighing pan must be replaced with a pan dedicated to checking and calibrating the balance (both are included in the standard equipment). The AP-12.5Y can calibrate not only 12-channel pipettes, but also single-channel pipettes.

The HX7.4 C scale is a solution based on a stainless steel PUE HX7 terminal (AISI 304) and a powder  (more)coated 4-load-cell platform. The terminal The terminal is characteristic for a 7” colour graphic display. Its novelty is a red-green 9-diode bar graph presenting the current net mass in reference to the scale range or preset min and max thresholds. At the back of the housing there are hermetic connectors of RS232, RS485, USB and Ethernet communication interfaces, plus digital inputs/outputs and analogue output. This enables cooperation with external devices such as: barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control superior IT systems. With use of the bracket you can either place the indicator at any flat horizontal surface, or fix it to the wall adjusting the tilt respectively to suit your needs. Databases Terminal’s system of information is based on databases: users, products, weighings, packaging, formulations, customers, ALIBI memory which guarantees stored data safety. The terminal's software allows carrying out processes such as weighing, parts counting, dosing, labelling, formulations and percent weighing.
