Product Description

XHV-15ST Canadian Freeness Tester is specifically designed to measure the dehydration rate of pulp suspensions,

evaluating the filtration performance of pulp based on Canadian Standard Free Degree (CSF) values. It is suitable for

quality control in the paper industry, R&D laboratories, and third-party testing institutions, ensuring standardized and

consistent pulp production processes.

Test Standards

ISO 5267-2/ TAPPI T 227

Product Features

l Precise dehydration analysis: Separate fibers and filtrate, quantify dehydration efficiency via calibrating the plate and flow nozzle to separate the fibers and filtrate.

l Temperature compensation technology (digital touch screen version): built-in temperature sensor automatically corrects environmental differences to improve data reliability.

l Modular design: The stainless steel frame is equipped with lightweight special plastic components, which are both durable and easy to operate.

l Multi-scenario adaptation: supports digital measurement to meet different experimental needs.

Technical Parameter

measuring principle	The suspension is dehydrated through the calibration perforated plate, the filtrate is diverted through the separation funnel, and the excess liquid is discharged through the side tube.
measuring range	Freeness (CSF): 0-1000 mL (touchscreen digital version displays temperature-adjusted CSF value and CSF value compensation based on pulp test concentration input).
accuracy	±1 mL
temperature compensation	supports dynamic temperature correction based on ISO/TAPPI standards.
Key structural parameters	Standard adjustment capacity: 1.5±0.2mL Overflow height: 50.8±0.7mm Water chamber diameter: 101.6±0.2mm Water filter chamber height: 127.0±0.2mm Valve control aperture: 4.8±0.2mm Separation funnel cone angle: 29.5°±0.5°
data interface	standard thermal printer test results and USB data output (optional).
power requirement	100-240V wide voltage, 50/60Hz, power consumption <25W.
operational environment	Recommended temperature: 10-40°C, humidity ≤80% RH (non-condensing).
Device material	Shell: 304 stainless steel; Core components: corrosion-resistant special plastic (resistant to chemical solvents, easy to clean).
Size and weight	330×380×1000 mm (length×width×height); gross weight including packaging: 60-65kg.
