Welcome to Tech-Long

Discover how we can help your organisation with any CSI requirement
Forensic Evidence

The basic principle for Forensic Evidence is “every contact leaves a trace” and specks of blood, fibres or fingerprints become silent witnesses against the criminal.
Expert Consultation

The Tech-Long team have been identified and recruited for their skills and experience in Policing, Forensics, Design and Engineering giving you full access to a unique range of experts.
Fluorescence Examination

A light source is required to excite fluorescence within the mark or substrate. Our Class 4 Lasers provide a range of wavelengths and power that out perform other light source options.

Why use Tech-Long?

Our products provide superior results in any crime scene
Standard Equipment

When analysing a crime scene,  Laser light will show up more forensic evidence than LED.  Vital evidence could be missed, using lower spec products.
