Superior Thermal Control and SafetyLHT bench top ovens integrate a double-wall insulated door with a silicon gasket, ensuring minimal heat loss and maximum user safety. Their automatic overheat cut-off system and reliable chromium-nickel wire heaters provide stable performance, while the microprocessor-based PID controller maintains temperature uniformity within 2C at 100C, even during long heating cycles. The equipment is also furnished with CE marking and ISO certification.
Adaptable and Efficient Oven DesignWith capacities ranging from 30 to 100 liters, the LHT series incorporates adjustable stainless steel shelves and a motorized blower for even heat distribution. Users benefit from the ovens digital timer, programmable up to 999 minutes, and its powder-coated mild steel exterior, enhancing durability. The digital PID display and semi-automatic automation grade further boost operational efficiency for various applications.
FAQs of LHT - High Temperature Bench Top Ovens:
Q: How do the LHT High Temperature Bench Top Ovens maintain uniform heat distribution?
A: These ovens utilize a motorized blower that circulates air within the chamber, ensuring all samples receive homogeneous heating. The double-wall insulated design with mineral wool further enhances thermal stability and consistency during the heating process.
Q: What safety features are included to prevent overheating?
A: To safeguard users and samples, the LHT ovens are equipped with an automatic over-temperature cut-off system. This feature automatically halts heating if the set limit is exceeded, preventing damage and enhancing laboratory safety.
Q: When should I use adjustable shelves in the oven, and how are they beneficial?
A: Adjustable stainless steel shelves allow you to accommodate different sample sizes and quantities at once, optimizing space and enabling efficient heating for larger or multiple items simultaneously. They are especially beneficial for varied experimental setups or changing throughput needs.
Q: Where can the LHT series be installed and used?
A: Thanks to their compact, bench-top design and robust construction, LHT ovens are suitable for installation in laboratory, research, and industrial settingswherever precise and reliable thermal processing is required.
Q: What is the process for setting temperature and timing parameters?
A: The ovens feature a digital PID controller with user-friendly interfaces, allowing for easy programming of temperature (between ambient +5C to 300C) and timer settings (0999 minutes). Simply enter the required parameters on the digital display, and the microprocessor ensures precision control.
Q: What are the main benefits of using the LHT High Temperature Bench Top Oven?
A: Key benefits include accurate temperature control (1C), energy efficiency (1.2 to 2.5 KW power consumption), safety mechanisms, uniform heating, ease of cleaning with a mirror-polished chamber, and compliance with CE and ISO standards for quality assurance.
