Sartorius Tare

This listing is for a Sartorius Tare CPA34001S Analytical Balance

The unit is in full working condition and is ready for immediate release.

This model offers a weighing capacity of up to ~34,000 g (34 kg) with a readability of 0.1 g.

It includes an automatic internal calibration (isoCAL) function, allowing the balance to self-calibrate at set intervals to maintain accuracy. The weigh cell is described as “monolithic weigh cell technology” which gives stability, precision and durability.

Large weigh pan: e.g., specification documents list a pan size of 400 × 300 mm for this model.

The housing is designed to be robust and chemical-resistant for tough lab environments.

Interface: it supports RS-232C / V24‐V28 serial interface for data logging, printing, external systems.

Fast response time: average response stated < 2 s in one specification sheet.

Tare function: full subtractive tare up to 100% of capacity is supported.

Applications & Use-Case

Given its capacity (34 kg) and readability (0.1 g), this balance is suited for large-capacity analytical weighing rather than ultra-fine micro-weighing. Typical uses could include:

Weighing bulk samples, large containers or vessels (e.g., large drums, tanks) where still a good accuracy of 0.1 g is required.

Industrial laboratories, QA/QC, production where large items must be weighed with decent precision.

Situations where the weighing pan size needs to accommodate large items (400×300 mm is relatively large).

Environments where interface to computer/printer is needed for logging and traceability.

Where regular internal calibration is a benefit to maintain accuracy over time without frequent manual external weight calibration.
