EDGe

EDGe is a non-nuclear, soil density, field and in-lab gauge to measure the density and moisture content of materials like aggregate, soil aggregate, compacted base or natural soil. It is used for determining the suitability of these materials for secondary roads / base aggregate for asphalt or concr...

ete. Humboldt's EDGe is a lightweight and user-friendly quality assurance / quality control (QA / QC) system that does not require nuclear technology. It includes one unit for lab use in determining Proctor values and another for on-site field measurements. These units work in tandem with a Microsoft app to ensure precise and accurate measurements. The brand's EDGe system establishes a direct correlation between Proctor test data obtained from a sample in the lab and readings of the same material taken in the field for consistent and reliable assessment of aggregate and soil samples for improved decision-making in construction projects.

Tru-Wate

Tru-Wate mud balance is a device used to measure the density of a fluid sample (cement slurry and similar fluids) accurately. The density of the fluid sample can be measured within a fixed volume under pressure by using the Tru-Wate balance. It pressurises the sample cup to reduce the presence of ai...

r / gas for a precise measurement of the slurry density that closely corresponds to the actual density in down-hole conditions. This density balance has metal construction for increased durability, accuracy and user-friendliness. It comes with a sturdy plastic case that protects the balance during transportation and provides a stable base for measurements.

How to install laboratory ovens and furnaces?

Choose a suitable location for the oven or furnace, considering ventilation and access to utilities.
Carefully review the manufacturer's instructions for installation guidance.
Ensure the electrical power supply meets the specified requirements.
Verify proper ventilation to dissipate heat and fumes.
Consult a qualified technician to connect gas or compressed air supply lines if needed.
Position and level the oven or furnace accurately.
Install necessary safety equipment as per manufacturer recommendations.
Follow the manufacturer's instructions to start up and calibrate the unit.
Familiarise yourself with operational guidelines and safety protocols.
Provide training to personnel and comply with regulatory standards.

What is the difference between a bunsen burner and a general purpose burner?

Bunsen burner and general-purpose burner serve heating purposes but differ in several aspects. Bunsen burner features a vertical metal tube with an adjustable air intake and gas nozzle. It produces a non-luminous Bunsen flame characterized by a blue inner cone and a less intense outer flame, which is relatively cooler. Primarily used in laboratories, Bunsen burners offer precise control for heating, sterilization, and specific experiments. In contrast, general-purpose burners encompass a broader category with various designs and flame characteristics. They find applications beyond laboratories, offering versatility for heating, melting, soldering, flame tests, and combustion reactions in diverse settings. The adjustability of Bunsen burners, including airflow control, allows users to regulate flame height and oxygen supply. General-purpose burners may vary in adjustability based on their design and intended use. Overall, while the Bunsen burner provides controlled and consistent flames in laboratory settings, general-purpose burners offer flexibility for heating applications in various environments.
