Description
Product Introduction:
The freeness tester is a specialized instrument used to measure the drainage characteristics of pulp. Based on the inverse relationship between the pulp’s freeness and the filtration rate of its suspension, this instrument enables the assessment of fiber morphology and the evaluation of the degree of refining.
The pulp freeness tester is a standard laboratory instrument designed according to the Schopper–Riegler method, which is a conventional technique for measuring the drainage rate of diluted pulp suspensions.
Reference standard:
1. ISO 5267-1 “Pulps — Determination of Drainage Properties — Part 1: Schopper–Riegler Method”
2. Relevant provisions of GB 3332, “Method for Determining the Consistency of Pulp”

YLZ-100 Microcomputer-Controlled Electro-Hydraulic Servo Curbstone Flexural Testing Machine
The YLZ-100 concrete curbstone flexural‑compressive testing machine is used to determine the flexural strength and flexural load of linear curbstones with a length of 1000 mm, as well as the compressive strength of curved curbstones and L‑shaped curbstones with a straight cross‑section. In accordance with JC/T 899‑2016 Concrete Curbstones, it can also be employed to conduct experimental studies on the flexural and compressive strengths of other materials.
The microcomputer-controlled high‑ and low‑temperature electronic universal testing machine consists of the testing machine mainframe, fixtures, a high‑ and low‑temperature chamber, and computer software. The temperature chamber is slid into the mainframe; after opening the chamber door, the specimen is secured in the dedicated fixture. The chamber then heats or cools until the specified temperature is reached.
