The Alchemie Conductivity Cell is a robust and accurate platinized cell. These highly repeatable cells provide accurate readings with fast response time. As applications demand reliable sensors, the performance of a typical Conductivity Cell depends upon the Platinum Black coating to produce a stable and constant voltage independent of the process conditions. Alchemie Conductivity cells stand up to these stringent specifications.

Use of Radio-nuclides with in-house verification of source strength is advisable due to the accuracy required for maximizing tumor cell death and minimizing healthy tissue damage. Well-type ionization chambers make it easy to establish source calibration procedures. For accreditation of institutes, some countries have made usage of Well Chamber a mandatory requirement.

The Brachytherapy Calibrator has been developed by CD Hightech in collaboration with Bhabha Atomic Research Centre, India and is tested at various leading hospitals. The unit can be used for the calibration of Isotopes in both HDR and LDR applications.The source holders provided would enable high reproducibility of the source position in the chamber. Tests conducted at hospitals confirm excellent performance of the unit.

The measurement of Patient Dose during Brachytherapy is a standard practice followed by hospitals all over the world.

Clinidose enables reliable Rectal Dose measurements with high degree of safety to the Patients.

Clinidose is a simple instrument to operate. Adjusting the digital display to zero ( in the absence of Radiation) is the only control that the instrument needs.

Clinidose has a built-in rechargeable Ni-Cd Battery supply. For protection from shocks to the patients, all dose measurements are performed while operating the unit on Batteries.

The CD Conductivity Housing has the widest available range of conductivity cell and NTC automatic temperature compensator options, making it ideal for high-purity water measurement with solution ground. The ultrasonic cleaner option is a plus for processes with deposit problems. The housings are available in SS316, Polypropylene and Teflon with numerous mounting configuration options, including in-line and immersion mountings. A guard ring tube protects the conductivity cell input from electrical leakages occuring due to submersed electrical equipment.

The CD SSD-92 is a Precision Dosimeter for the Calibration and Quality Assurance checks of Radiotherapy machines. The instrument is supplied with a standard 0.5CC Ionization Chamber.

The CD Ionization Chambers are connected to the SSD-92 by BNC plugs. The instrument can be used with many types of chambers. A wide range of Ion Chambers are available which includes Chambers of different volumes, Parallel Plate Chambers, Well Chambers etc. CD SSD-92 can also be used with solid state detectors.

Over 80 CD Dosimeters have been supplied in INDIA and it is normal to find their calibration accuracy to be within 1% even after many years of usage.

The SUPERSTIR uses CMOS TECHNOLOGY for accurate SPEED CONTROL assuring trouble free continuous operation. The free spinning rotating magnet spins a Teflon stirring bar to stir liquids in open and closed vessels.

The solid state FEEDBACK CONTROL SYSTEM maintains excellent speed stability despite viscosity or volume change or voltage fluctuations. The SUPERSTIR operates at FULL HIGH TORQUE at all times through the entire range of 100 to 1400 r.p.m. special circuitry prevents sudden change of speed to keep the stirring bar from spinning out.

A unique REVERSE control provides the automatic change of direction of stirring using 30 sec. to 3 min. cycles. In the reversal mode, a CATCH BACK feature is also incorporated. If the stirbar flies out, it is automatically caught back during the next cycle, ensuring a fail-safe unattended stirring operation.

The timer control is settable from 5 min to 2 hours. for automatic stoppage of stirring. The timer can be RESET and RESTARTED by a front panel switch.

The LOW PROFILE design uses superior stainless steel top with no seams above the base and also an anti skid rubber base. This minimizes handling hazards and avoids awkward heights for adding materials to the stirred liquid.

CD Xrossline Lasers - new generation of diode Lasers, are a new step in diode laser technology. CD Xrossline is the first diode laser for patient alignment made in India. it is designed to meet the highest demands on visibility, stability and reliability. Xrossline with a wavelength of 635 nm, offers a very good visibility. the small size makes it ideal, for use as Cross, Sagittal, or even a back Pointer mounted on the gantry.

The Xrossline Lasers is the right choice for the lighting conditions normally found in treatment rooms.

The system can be used immediately when switched on since it needs no warm-up time. Xrossline Lasers are Easy to install. They have built-in adjustments for horizontal and vertical positioning.

The angle can easily be adjusted with three precision screws. An optional bracket allows further adjustment of angle to ±75° allowing the laser to be mounted in arbitrary angle. The expected lifetime of Xrossline Lasers is more than 10 years, and it a very cost effective choice.

Sagittal Red-S is a Sagittal laser and the Xrossline Red-X is a cross laser.
