Constant Temperature Water Bath For Marshal Test With Digital Controller

Constant Temperature Water Bath For Marshal Test With Digital Controller

Model Number : EIE-406-M

The water bath is a critical component in Marshall testing of asphalt mixtures, ensuring samples are conditioned at the prescribed temperature before testing for stability and flow. Each standard, including ASTM D1559, ASTM D5581, AASHTO T245, EN 12697-12, and EN 12697-34, emphasizes precise temperature control to replicate field conditions and ensure consistent, reliable results.

Description:
  • Double walled water bath specially designed for Marshal Stability Test. The inner chamber is made of mirror polished Stainless Steel S.S. 304 Grade and the exterior body is fabricated from Mild Steel with powder-coated finish. The gap between the inner chamber and exterior body is provided with glass wool insulation to prevent thermal heat loss. Temperature is controlled by a Microprocessor based Auto-Tune Digital temperature controller cum indicator, while the constant-speed stainless steel stirrer maintains uniform temperature distribution within the bath chamber.
Applications:
  • Specially designed for Marshal Stability Test and for maintaining controlled temperature during the testing process.
Apparatus Details:
  • Double walled water bath with mirror polished S.S. 304 grade inner chamber, fully argon welded construction, Mild Steel powder-coated exterior body and glass wool insulation. It is fitted with a Microprocessor based Auto-Tune Digital temperature controller cum indicator and constant-speed stainless steel stirrer for uniform temperature distribution. Heavy platform is provided for accommodating Marshal moulds and breaking head assembly. Selected variants are supplied with a handle for easy lifting and placement of moulds, and a drain valve is provided.
Compliance Standards:
  • ASTM D5581, ASTM D1559, AASHTO T245, EN 12697-12, EN 12697-34
