The EMA Series moisture analyzer uses infrared halogen heating to rapidly determine moisture content from 0 to 100% across a temperature range of 40°C to 200°C. Features a 5-inch full-color touchscreen, multiple heating modes, 500-record data storage and RS232 output. Available in five models from 5mg to 0.1mg readability, covering standard and high-precision laboratory applications.
The EMA Series moisture analyzer is a halogen-heating instrument designed for rapid, accurate moisture content determination in pharmaceutical, food and beverage, chemical and industrial materials testing. By combining a high-efficiency infrared halogen lamp with a precision weighing sensor, it calculates moisture content directly from the weight loss during heating — delivering results significantly faster than traditional oven-drying methods without sacrificing accuracy.
All EMA models feature a 5-inch full-color touchscreen with intuitive interface, multiple heating modes and a comprehensive set of display options including moisture content (%), solids content (%), regain rate (%), wet weight (g) and dry weight (g). Standard and gradual temperature ramp modes, combined with auto and manual shutdown options, allow the heating profile to be tailored to different sample types and laboratory protocols.
The EMA Series spans five models covering maximum capacities from 120g to 220g and readabilities from 5mg (EMA105D) down to 0.1mg (EMA1204), with the EMA1204 using an electromagnetic force sensor for the highest weighing precision. All models share the same core feature set and are compatible with the optional PT200 serial printer for GLP-style report output.

Both have a 120g capacity and the same core feature set. The EMA105D has 5mg readability and 0.10% moisture readability — suitable for general-purpose moisture testing where the highest moisture resolution is not critical. The EMA123 offers 1mg readability and 0.01% moisture readability, providing ten times the moisture measurement resolution for more demanding laboratory applications. For most laboratory work, the EMA123 or above is recommended.
Both have 120g capacity and 1mg/0.01% moisture readability. The EMA1203 uses a strain gauge sensor, while the EMA1204 uses an electromagnetic force sensor — the same sensor technology used in high-precision analytical balances. The electromagnetic force sensor in the EMA1204 provides superior long-term stability, faster response and better performance at the extreme low end of sample weight, making it the preferred choice for the most demanding pharmaceutical and research applications.
Halogen infrared heating concentrates heat directly onto the sample surface, raising temperature rapidly and evenly. A typical moisture analysis with the EMA Series takes 3–15 minutes depending on sample type and moisture content, compared to 1–4 hours for conventional oven drying. Results are equivalent for most materials, though certain samples with thermally sensitive components or complex moisture binding may require protocol validation against the reference oven method.
Standard mode ramps the temperature immediately to the set value — suitable for most stable, non-sensitive samples. Gradual mode increases temperature progressively to avoid surface hardening or spattering in samples that are sensitive to rapid temperature change — recommended for high-moisture or fatty food samples. Timed shutdown allows a fixed duration test rather than automatic endpoint detection, useful when a standardised test time is required by protocol.
Yes. The EMA Series uses external calibration via the optional 100g F2-grade calibration weight. Regular calibration is recommended to maintain weighing accuracy, particularly after moving the instrument or when ambient temperature changes significantly. The optional PT200 printer can print calibration records for GLP documentation.
The EMA Series is suited to moisture determination in pharmaceutical raw materials and finished products, food and beverage ingredients, chemical powders and granules, polymer and plastic materials, paper and wood products, agricultural products and feed materials. Samples that are highly volatile, thermally reactive or require Karl Fischer analysis may need alternative moisture determination methods — contact our application engineers for guidance.
