With a modest beginning in 1986 in 1200 sq ft workshop area, “Multispan Instruments Company” was founded on the principles of providing user-friendly & “frugal” innovation based panel mounted Temperature controllers for injection moulding, extrusion units and other plastic processing machinery manufacturers in India. In period, 1990-1995 company widened its product offerings like Digital timers & counters which complimented Temperature controller in control panels.
During 1995-2000, with more than 50 products, the company R&D efforts transitioned these products to micro-controller based design from solid-state based technology. In the same period, the company setup area was totaling around 3500 sq ft area. In 2003, PID based technology was introduced in Temperature controlling behavior based on practical industrial tests carried out for various indigenously manufactured machine types suitable as per Indian industrial atmosphere. With 100+ products, Multispan products were now used across industrial machines countrywide. Factory & office was expanded to more than 10000 sq ft area.
By 2005, a varied range of temperature controller models based on PID behavior was launched suited for each Indian manufactured machine type with different price points. By 2010, with product portfolio reaching around 200 models, sensitive industrial applications were also covered with high-featured products that include Multi-channel temperature scanners, Sequence timers, Multi-parameter energy meters along with an option of computer & printer connectivity. In April 2013, a new 25000 sq ft production facility was inaugurated to satisfy the growing production targets as per market demands.
Standard quality & reliability policies are laid into ISO standards & audits by the management team to ensure that quality assurance is maintained anytime.

About Temperature Scanner :
A Temperature Scanner is a device that measures more than one temperature points or multi-channel. It is actually a multi-channel indicator that measures and displays signals of each channel one-by-one up to last channel and then returns to first channel and continues the process cyclically. This continuous cyclic process of measurement is called scanning. Temperature is most widely measured parameter in industry. By using a temperature scanner, temperature of multiple points can be measured in a single unit thus saving cost and space. Thus Temperature scanners are also called as multi-point indicators / scanners. Temperature Scanners are essentially based on digital technology or microprocessor/ microcontroller based. It is capable of measuring temperature from resistance temperature sensors like RTD Pt100 or from different types of thermocouples like J, K, R, S, T, B, E and N.
