PID Temperature Control

The LCD Digital Heating Magnetic Stirrer with Timer (MS‑H‑ProT) is a high‑performance, programmable benchtop instrument engineered for accurate, safe, and efficient simultaneous heating and stirring in clinical diagnostics, pharmaceutical quality control, analytical chemistry, and industrial research laboratories. Featuring a 5‑inch (φ135 mm) ceramic‑coated stainless steel work plate, this PID‑controlled hotplate stirrer delivers a heating range from room temperature to 340 °C (±1 °C accuracy in 1 °C increments) and a digital stirring range of 100 to 1500 rpm (±1 rpm resolution), with a maximum stirring capacity of 20 litres of water.

Every LCD Digital Heating Magnetic Stirrer with Timer (MS‑H‑ProT) is individually factory‑calibrated and supplied with a calibration certificate traceable to international standards. The high‑resolution backlit LCD display simultaneously shows set and actual values for temperature, speed, and timer, providing complete operational visibility at a glance. The ceramic‑coated stainless steel work plate resists strong acids, strong alkalis, and organic solvents, providing rapid, uniform heat distribution without localised hot spots, while the maintenance‑free DC brushless motor (spark‑free) ensures ultra‑quiet, vibration‑free, long‑term reliability across the full 20‑litre capacity.

Key user‑focused safety features include dual independent safety circuits (redundant safety) for over‑temperature protection (user‑settable safety temperature cut‑out, 360 °C hardware cut‑off recommended), an independent residual heat warning indicator (“HOT” flashes on the display at >50 °C and continues even after the unit is turned off, if still connected to mains, until the plate is safe to touch), and IP21/IP42‑rated housing (check specification) offering basic to advanced splash and dust protection. An optional PT1000 external temperature sensor (±0.2 °C accuracy) provides precise closed‑loop control of the actual sample liquid temperature. An RS232 data interface enables remote PC control and full GLP‑compliant experiment documentation. A programmable timer (1 min‑99 h 59 min) enables fully unattended operation for extended‑duration stability studies and QC protocols, with the ability to stop heating at the end of a timed run while continuing stirring to protect heat‑sensitive samples.

With a compact footprint (160 × 280 mm), moderate weight (2.8 kg), and a universal power supply (100‑240 V, 50/60 Hz), the MS‑H‑ProT occupies minimal bench space while delivering exceptional performance suitable for demanding clinical and research workflows. The instrument is manufactured under ISO 13485 and ISO 9001 quality management systems, meets international safety standards (TÜV‑certified), and is backed by a 2‑year manufacturer’s warranty.

For the clinical laboratory scientist, pharmaceutical QC chemist, and research scientist, the MS‑H‑ProT delivers the modular versatility, large‑batch processing capacity, and true regulatory‑grade safety required for sample digestion for trace element analysis (blood lead, urine cadmium), bulk gel melting, and large‑scale dissolution testing. For the patient, the reliable, accurate, and safe thermal processing of this TÜV‑certified instrument ensures that life‑saving diagnostic tests and pharmaceutical therapies remain consistently reliable and reproducible, directly supporting effective clinical decision‑making, appropriate treatment selection, and patient safety.
