Automatic Moisture Analyzer - ToronMA™ A Series
ToronMA™ A Series automatic moisture analyzer applies the drying loss method with halogen lamp heating across a 40–230°C range and 1°C step temperature control. Weighing precision is 1mg on standard models and 0.1mg on Pro models, with moisture readability of 0.01% and 0.001% respectively. A 7-inch HD touchscreen displays the live drying curve, GLP/GMP-formatted results, and all eighteen functional settings. Standard and Pro variants are available with a dual-drive automatic door that opens and closes electronically.
GLP/GMP result recording captures sample name, company, contact information, and test parameters with each reading, storing 200 test reports and 200 sample programs onboard. Administrator and operator password tiers control access to settings and historical data for multi-user and regulated-environment use. Automatic timed internal calibration is available on the Pro+ model; all models support one-click preheating and temperature calibration without a calibration sample. Built-in testing programs cover standard material profiles, and custom programs are saved for repeat analysis of defined sample types.
The 400 × 240 × 185 mm housing holds the φ100 mm drying pan, halogen lamp, and dual-drive cooling fan in a compact bench-top form at 8 kg. RS232 is standard for GLP printing and data transfer; USB is optional, along with compatibility for thermal and label printers. The ultra-quiet dual-drive fan cools the drying chamber after each test cycle, accelerating readiness for the next sample. A CN/EN language setting and date/time stamping support documentation workflows in both Chinese and English-language environments.
Automatic Moisture Analyzer - ToronMA™ A Series Applications

Automatic Moisture Analyzer - ToronMA™ A Series Key Features
The ToronMA™ A Series packs eighteen functional settings into a 7-inch touchscreen moisture analyzer with GLP/GMP output, halogen lamp heating, and automatic door options.
- Drying Loss Thermogravimetric Method: internationally recognized technique measures mass loss during controlled halogen lamp heating, providing rapid moisture results without the multi-hour cycle of oven-drying methods
- 7-Inch Full-Color HD Touchscreen: icon-driven interface accesses all eighteen functional settings, sample programs, historical data, and real-time drying curves from a single display panel
- Halogen Lamp Heating (40–230°C at 1°C Steps): radiant halogen heating reaches the set temperature rapidly and distributes heat uniformly across the φ100 mm pan for consistent drying across the sample surface
- Four Test Modes: Standard, Fast, Soft, and Steps modes adapt the drying profile to different sample types, heat sensitivities, and moisture content levels
- Four Stop Modes: Automatic, Manual, Timing, and Custom stop options give the operator precise control over when each drying cycle ends
- Dual-Drive Automatic Door (Selected Models): electric dual-drive mechanism opens and closes the drying chamber door without operator contact, reducing vibration on the weighing cell during sample loading
- EMF Sensor (Pro Models): electromagnetic force restoration cell achieves 0.1mg weighing precision and 0.001% moisture readability for high-precision pharmaceutical and chemical moisture testing
- High-Accuracy Load Cell (Standard Models): precision load cell delivers 1mg weighing resolution and 0.01% moisture readability for standard pharmaceutical, food, and industrial moisture applications
- Auto Timed Internal Calibration (Pro+ Model): built-in calibration weight deploys automatically when the EMF cell detects temperature-induced drift, maintaining weighing accuracy throughout extended use
- GLP/GMP Data Recording: each result is saved with sample name, company, operator identity, test parameters, and date/time stamp for complete audit trail documentation
- 200-Set Onboard Storage: stores 200 test programs and 200 test reports, supporting high-throughput laboratories running multiple sample types without external data management
- Administrator/Operator Password Access: dual-tier login controls access to settings and historical data, supporting multi-user and regulated-environment operation
- Real-Time Dynamic Drying Curve: touchscreen plots moisture content against time throughout the cycle, allowing the operator to monitor drying rate and confirm sample equilibrium
- One-Click Preheating and Temperature Calibration: preheats the empty pan to the test temperature before sample loading and performs temperature calibration without requiring a calibration sample
- Built-In Sample Testing Programs: pre-configured material profiles are available for selection; custom programs save test parameters for repeat analysis of defined sample types
- Ultra-Quiet Dual-Drive Cooling Fan: cools the drying chamber after each cycle to accelerate the unit's readiness for the next measurement
- Label and Thermal Printer Compatibility: RS232 (standard) and optional USB support connection to label printers and thermal printers for GLP-format result labels
- CN/EN Bilingual Interface: switchable Chinese/English language setting supports operation in different regional laboratory environments
- Anti-Vibration Design: mechanical construction minimizes the effect of external bench vibration on the weighing cell throughout the moisture measurement cycle
Theory and Method
Moisture analyzers using the drying loss method determine moisture content by continuously weighing a sample during heating until mass stabilizes. The ToronMA™ A Series measures initial sample mass, tracks mass loss throughout the drying cycle, and calculates moisture content as the percentage of mass removed relative to the original weight. A halogen lamp delivers rapid, uniform radiant heat to the φ100 mm pan, reaching set temperature faster than convective ovens. The sensing cell monitors mass continuously, generating a real-time drying curve on the touchscreen.
Four test modes address different sample types: Standard completes the full drying cycle; Fast applies higher heating for heat-tolerant materials; Soft uses gentler conditions for heat-sensitive samples; and Steps sequences temperature-time segments for complex materials. Stop mode (Automatic, Manual, Timing, or Custom) gives the operator control over cycle termination. Temperature spans 40–230°C at 1°C increments, with a thermal resistance sensor maintaining the set point throughout. Anti-vibration construction and the dual-drive door reduce disturbance during the weighing phase.
Standard A Series models use a high-accuracy load cell; Pro models use an EMF cell for 0.1mg weighing precision and 0.001% moisture readability. The EMF cell uses null-deflection force balance rather than strain gauge deflection, providing greater stability at higher weighing resolution. The Pro+ model adds fully automatic timed internal calibration; all other models calibrate externally with a user-supplied weight. One-click preheating warms the empty pan to the test temperature before sample loading, reducing the time between measurements.
