Laboratory COD Digester (15 Sample Tubes)
Model / Reference:
TI-101 (15 TUBES)
Factory Calibrated & Tested
TEMPO Laboratory COD Digester is designed as per standard IS & ASTM methods for Chemical Oxygen Demand (COD) digestion in wastewater, industrial effluent, and water treatment laboratories. Built with a heavy-gauge powder-coated outer cabinet and double-wall glass wool insulation for maximum thermal efficiency. Features an anodized solid aluminium block holding 38 mm diameter sample tubes, controlled by a high-precision microprocessor PID temperature controller with an integrated 0–120 minute digital timer.
