Product Description

Overview: This manually-operated apparatus, also known as the dish-type liquid limit instrument, is specialized equipment for determining the liquid limit of soils and is widely used in civil engineering applications. The device primarily consists of a brass dish, a hard rubber base, an impact mechanism (with cam and counter), and a grooving tool.

Driven by an electric motor, the dish drops at a rate of 120 blows per minute (tolerance: ±15%), with a built-in blow counter. Its core function is to determine the moisture content at which soil transitions from the liquid to plastic state.

I. Scope of Application:
This standard specifies the test method for determining the liquid limit of soils. The result must be based on at least three separate tests and the preparation of a flow curve. Unless explicitly permitted for the soil being tested, the dish-drop method shall be used.

II. Definitions:
The liquid limit of a soil is the moisture content defining the boundary between the liquid and plastic states. Artificially defined as the moisture content at which two halves of soil paste flow together for a distance of 12.7 mm when the brass dish is dropped 25 times from a height of 1 cm at a rate of 2 seconds per drop.

Included Components:
Liquid Limit Apparatus, Brass Dish and Mounting Base, Grooving Tool with Gauge, Porcelain Evaporating Dish (114.3mm), Spatula (76.2mm x 19mm), Moisture Proof Containers, High Sensitivity Balance.
