HEAT OF HYDRATION APPARATUS - WITH DAQ AND PC CONNECTIVITY - IS 4031, IS 11262

Compliance :

The apparatus is designed to meet and exceed the requirements of the following standards:

1. IS 4031 (Part 9) – Heat of Hydration of Cement
2. IS 11262 – Heat of Hydration of Cement
3. ASTM C186 – Heat of Hydration of Hydraulic Cement
4. EN 196-8/ EN 196-11

Premium Advantage Summary :

1. The integration of a touch-screen controller with automatic data logging, internal data storage, and digital data transfer elevates the system from a conventional calorimeter to a fully automated, audit-ready Heat of Hydration testing solution, offering:
2. Zero operator dependency during test execution
3. Accurate capture of transient thermal behavior
4. Complete digital traceability of test data
5. High confidence during NABL, ISO/IEC 17025, and third-party inspections
6. This premium configuration is strongly recommended for cement plants, accredited laboratories, government quality control agencies, and R&D centers where precision, repeatability, and data integrity are non-negotiable.

Operator Skill Requirement :

1. No manual intervention required during the test.
2. The operator only initiates the test; all measurements, logging, and data storage are fully automatic, ensuring consistency and eliminating operator bias.
3. Display & Calculations
4. The controller continuously displays and records:
5. ΔT (Temperature rise)
6. Minimum temperature
7. Maximum temperature
8. Mean temperature values
9. Alarm System
10. Audible alarm provided to alert the operator if temperature limits exceed the permissible range.

Apparatus Construction and Features :

The complete Heat of Hydration apparatus consists of the following precision-engineered components, designed for reliable and reproducible calorimetric measurements:

1. Digital Thermometer with Data Logging
2. Temperature resolution: 0.001 °C
3. Enables accurate detection of minute thermal changes throughout the test duration.
4. Dewar Flask (Open-Mouthed Type)
5. Mounted within a high-efficiency insulating medium and housed in a robust wooden enclosure.
6. Hinged wooden housing allows easy removal or replacement of the Dewar flask without disturbing the calorimetric setup.

Stirring System :

1. Constant-speed motorized stirrer fitted with a glass propeller-type stirring rod.
2. Ensures uniform temperature distribution in the calorimetric liquid and adequate suspension of solid reactants in the acid mixture, minimizing thermal gradients and measurement errors.

Accessories :

1. Cork stopper
2. Glass funnel
3. Insulated container assembly

Technical Specifications – Controller & Data Logging System :

1. Controller: 4-inch Touch Screen Controller for intuitive operation and real-time monitoring
2. Data Logging (Points): Temperature values are automatically logged at pre-determined intervals within the controller, eliminating manual recording.
3. Data Storage : All logged temperature data are securely stored in the internal memory of the controller for complete test traceability.
4. Data Transfer : Logged data can be:

Transferred to a computer via USB interface, or

Connected to a computer through serial communication port for live monitoring and data extraction.
